Warning, this review is better read by those who have seen the movie.
Where do I start with this one? House of Blood a.k.a. Chain Reaction kept surprising me. German make-up effect master and horror filmmaker Olaf Ittenbach made this a couple of years ago, so I expected a foreign horror gorefest. First of all, it's actually completely in English, the gore is nowhere as extreme as I expected and it actually kept me watching because of its story.
So four prisoners have just escaped a transport vehicle by it having an accident and giving them an opportunity to pounce. What are the odds of that happening? The prisoners question this, but it turns out the odds are quite good. The vehicle also collides with the car of a doctor. It's a good thing because one of the prisoners has been badly hurt in the ensuing firefight with the cops. They go on the run with the doc and end up at the worst house they could've possibly ended up at. Once again, what are the odds? Maybe not so low, once again.
Overall: 2.5 out of 5. I felt extra protective of it because of the undeserving bashing it received, just like another horror movie called one of the worst: Five Across the Eyes. That movie is brilliant goddammit!
