Very creative and well done special effects, but the acting and storyline was definitely lacking. I felt like I was watching a loop for most of the movie. Let's stay here, let's go downstairs, let's go back up, let's stay here, let's go down again, get back upstairs quick, we forgot how dangerous it was down there, let's stay here, let's go again. And who the hell would think that the water is like an automatic safe zone?? The constant push from Jarrod to get to a boat was stupid. There are so many smarter options they could have come up with. The ending was cool except for that fact that why in the hell is he still basically himself when noone else seems to be?
