This is not at all a bad horror movie. I have to admit that the movie didn't seem very interesting at first, but seeing it was written and produced by Guillermo del Toro, I was more interested in seeing it. I'm glad I did. It starts off really creepy and gruesome, but the more you watch, the less you're scared. It is, indeed, very creepy throughout the whole 90 minutes, but as soon as you get a good look on the creatures, you're kind of, not really scared of them anymore. The plot is interesting, though many cliches happen. The atmosphere is great and the movie looks beautiful and stylish! The acting is quite good, even from Bailee Madison. All in all, a good horror movie which could've been better if it avoided some cliches and didn't show the creatures so early. I would recommend this mostly to horror fans.
