This is a solid little creepy film that will have staying power even when big budget horror films are long forgotten. I will definitely watch it again in the future. I went into it expecting it to be poorly done stupid horror (ala 13 Ghosts), but I was quite surprised at how it held up. The acting is good without being overdone; the characters don't become cliched. And the overall sense of isolation and fear is believable. The look of the film and the characters harkens back to the feeling of "Das Boot," but it's quite a different story (I'm not equating the two by far...Das Boot is a masterpiece...this is a very well done B-picture). And as others have mentioned, the small details are correct, which makes it all the more fun to watch. The compartments, controls and hatches are in the right places. As far as I can tell, they filmed this in a real WWII submarine...or a 100% correct set piece. I've been to the USS Pampanito museum (a real WWII Balao class sub here in San Francisco) several times and it's pretty much the spitting image of the sub in this film. They also took care to be fairly correct with protocol, i.e. who would be standing where and doing what in the compartment when an order was given. You should definitely check out the deleted scenes on the DVD too...they're actually quite good and I'm disappointed they were left out of the final cut. Too bad this film didn't get more PR...it's far better than your average "horror film" being made these days.
