A half human, half animal creature, product of failed genetic experiments, breaks loose on a hospital where a group of med students are spending the night.I saw a very dark and grainy copy of this film and I think it made it more effective. The premise of the story was cool, there were some dark and creepy parts but the overall execution is very weak. It seems the main problem was the script since the story was told in a kind of messy, rushed and uninteresting way. The acting was OK and the film had some nice gory stuff although nothing extraordinary or over-the-top.The film looked like they wanted to follow a typical Hollywood formula but failed (don't feel bad though, since Hollywood fails more than often). I think Latin American countries should focus on more original and folkloric stories to creep us out.Overall, it was a nice effort for an apparently minimal budget but the potential it had was, mostly, wasted.
