Very very predictable, including the post credit scene !!!

Absolutely Fantastic

Although it has its amusing moments, in eneral the plot does not convince.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

After surviving a prison bus crash out in the wilderness, a doctor is taken hostage to tend to a wounded inmate, only for the house they choose to seek shelter in belongs to a race of bloodthirsty demons and dispatch the group one-by-one.This was an overall enjoyable and entertaining effort, though there were some pretty big flaws present. The biggest one here is the needless circular story-telling that happens, as the film goes through two different versions of what happens are repeated again in the course of the running time. This is a part of the film's rather troubling storyline in general as getting the second half of the story to repeat the first half in order to tell everything again really makes no sense as it employs the exact same set-up with the exact same outcome both times over, and it exemplifies the problem with the rest of the film's storyline and structuring issues. Not only does this one repeat that facet wholesale, but it skips around repeating scenes from earlier to show the accident that stranded them there and then later on going back showing the group getting free by shooting their way to freedom which are simply inserted into random sections of the film and altogether simply makes for a jumbled storyline. As well, the fact that hardly any of the characters are that likable makes for a tough watch when it's really hard to understand why they're together traipsing through the woods simply bullying each other or going to such extremes simply displaying such utter stupidity in their decision-making that really adds to their unlikable nature and really troubles the film, but it's not a rather huge issue. The greatest plus for the film, though, is that none of that matters when it gets going and starts to deliver the goods, and this one does a great job at producing copious and over-the-top quantities of gore and bloodshed. This here is quite varied about where it comes from, ranging from crude surgeries of amputated limbs to hearts being ripped out, decapitations, gunshot wounds and much, much more here that make this a real gorehound's dream. That also means a lot of action scenes here with plenty of confrontations between the two sides, starting with the first group appearing there and the family turning into the creatures fighting off the group in extended brawls throughout the cabin which is quite fun, while the second visit there brings out the more adventurous brawling that shows the group being completely overwhelmed from the start, and it's quite a bit of fun especially with the peculiar group of demons present they must battle. Throw in an atmospheric house for the location as well as the great monster make-up and it's got enough to make it interesting over those few flaws.Rated R: Extreme Graphic Language and Extreme Graphic Violence.

Olaf Ittenbach slowly but surely succeeds in making every movie he makes look better and better. For a low budget direct-to-DVD flick, the cinematography of "House Of Blood" (aka "Chain Reaction") looks mighty good. Excellent and gory splatter effects too (but sadly they are mostly displayed in only two main grotesque fighting sequences). The story, on the other hand is pretty damn thin and takes itself a bit too serious for this type of film. Still, it kept my attention and splatterfans will be pleased too. Americans might be careful renting this one, because the version currently available in mainstream videostores is heavily cut. They'll be missing out on some juicy stuff. Just keep making 'em, Ittenbach, I'll be watching them. -- PS: Since this comment dates back to 2007, I've seen Ittenbach's "Dard Divorce" in the meantime already. I liked "House Of Blood" a bit better.

While driving on a lonely road a bus with dangerous inmates from Seattle, the driver crashes on a car driven by Dr. Douglas Madsen (Christopher Kriesa) and the three prisoners leaded by Arthur Palmer (Simon Newby) escape and execute the security guards. However, Arthur's brother Spence (Luca Maric) is shot, and the criminals decide to abduct Dr. Douglas to take care of Spence and walk to North in the direction of the Canadian border. They find an old cabin in the middle of the woods inhabited by a weird family that speaks ancient English and advises the group to leave the place while they can. The strangers transform in flesh-eater monsters and kill the criminals, but the local Alice (Martina Ittenbach) spares Dr. Douglas and saves his life. He is found by the police and he is interrogated by a police officer (Jürgen Prochnow) that does not believe on his words and he is sent to the prison in Seattle. While in a bus with dangerous inmates, the bus crashes on a car and the story repeats like in a déjà vu for Dr. Douglas and the criminals."House of Blood" is an extremely violent and gore, with scary and gruesome special effects. Unfortunately the acting is uneven, with good but also awful performances. The screenplay and the story are flawed, since what could be the possibility of another identical accident in the same lonely road in the same circumstances? But there are good points in the story and with improvements and better actors, this movie would have a great potential. I can not say that I hated or that this movie is totally bad, but the story indeed deserved improvements. My vote is five.Title (Brazil): "Casa de Sangue" ("House of Blood")

Olaf Ittenbach is a fairly gifted special effects wizard; there are quite a few movies to confirm this statement. But at the same time he's an absolutely terrible director and, unfortunately, there are several movies to confirm that statement as well. Somebody really ought to tell him - tactfully - that he isn't cut out to sit in the director's chair and that he should exclusively focus the rest of his career on make-up effects. The gory bits and nauseating effects form the only highlights in "House of Blood", as the rest of the film is one major pitiable effort, complete with poor plotting, total lacking of coherence & suspense and probably the worst acting performances you've ever seen in your life. The basic premise is already rather stupid, and then still the script has the pretension to appear intelligently structured and even poetic! The official title (although "House of Blood" is a much more suitable one) refers to the unlikely chain of reactions caused by a small event. A dead bird falls from a tree and causes a rock to roll down a hill and into the windshield of a car. This subsequently results in a collision with a prison bus and all hell breaks loose. Four heavyweight criminals escape, take a doctor hostage and end up in a farmhouse where time seemingly stood still. The people there, wearing medieval outfits and talking with a strange accent, turn out to be bloodthirsty demons and repulsively kill the unwelcome visitors. The doctor escapes, but naturally the investigating police detective (Jürgen Prochnow, of all people, he must have been desperate for work) doesn't believe his story and arrests him. Next thing he knows, the doctor is sitting in a prison transport bus and the whole nightmare starts over. What, is this supposed to be some kind of surrealistic fairy-tale or something? All the characters, whether good or evil, are insufferable and you'll secretly wish they will all die an excruciatingly painful death. Who knows, maybe your wish is granted. My best advice is to try and totally neglect the ridiculous plot and just fully enjoy the grotesque gore! We're treated – in great detail – to faces getting smashed to pus with rocks or shot to slush with shotguns, wild axe-decapitations, ripped off testicles, torn open throats and much more. Utter garbage, but exhilarating & inspiring grossness… At least it's something.
