I have to say I saw this on iTunes as a new title. About half of the stuff iTunes recommends is good and half is crap (cough cough The Void). Anyhoo I love creature features and I have to say it's like a cross between the descent and deep rising and life? I can usually spot a B movie because the editing is weird and the dialogue is terrible and the acting isn't great and the story is boring. This took off quickly and I was never bored. I thought the acting and writing and story was too notch. This is one of the few B movies I've thought was watchable and fun. If you like creature horror/thriller you'll love this!
