Curiosity kept me watching
19 November 2015 | by neilcarlinSee all my reviews

Despite the warnings from negative reviews and low IMDb rating i watched it anyway... I've always liked Eli Roth mainly for his near show stealing appearance as 'The Bear Jew' in Tarantino's Inglorious Basterds and his movies, though never groundbreaking for me, offered playful b-movie fun. His efforts here seemed to diminish after the initial creation of suspense. Once we move to the second act the script loses any credibility and little is left for creation of further suspense. It's almost as if the idea was to get Keanu to behave somewhat like Nicholas Cage in OMG mode. That idea i couldn't shake and ironically it became what kept me entertained, imagining cage instead of reeves, which wasn't too hard as Keanu seemed to channel the spirit of the rage cage as if he were possessed by him. Don't let my mention of cage fool you, the acting in this movie is sub par, if Keanu isn't The Wicker Man he's the wooden man and the girls act like female villains in a made for TV batman movie. In summary; I found a few things Keanu said in a serious monologue quite laugh out loud funny and the use of a popular pixies track at the end credits reminded me of a student movie using cool music to be cool. All it did was remind me of it's already iconic use in one of my favorite movies. The movie was just bad enough to enjoy it's shitness or i'd have not sat through it. Avoid this if you get offended by crap movies but I'm almost recommending you to watch this for the points I mentioned for your own curiosity. The movie stuck in my mind enough for m to waste time writing this review, i wonder if that was Roth's intention for the audience or he actually took this movie seriously.
