This film looked like alot of fun and at the end of the day that's all it is. A great film to kick-back with some fellow horror buddies, load up on pizza and have fun with.
It's funny, at times quite bad-arse and purely campy.
It also features a great cast, which is part of why the film works as well as it does. Ryan Kwanten, Steve Zahn, Peter Dinklage, Summer Glau, Jimmy Simpson...even the supporting actors are perfect for their roles. A film like this hinges on it's cast, and this one worked splendidly.
Unfortunately not everything works. Some parts of the film are just way to cheesy to work and the special effects really weign in some places. Especially the ending, which features a pretty fake-looking monster. But I do have to applaud the director for not using CGI and actually attempting to put some soul into the effects.
It's not a complete home-run and it will never be confused for high art, but it is fun, funny entertainment. Sometimes that's enough.
