It's a shame....
It really is a shame when we live in such an immediate gratification society that any film that isn't non-stop action or filled with tons of CGI grue is blasted as boring!! Crawl really is a masterful, atmospheric, and like the director has stated, "thinking man's" Thriller. I know how if you like a film on IMDB that most hate, you are immediately accused of having something to do with the production of the film. Believe me, I haven't, I am just a life-long film fan, that found this one to be very good, in fact, I rated it an 8. If you like good thrillers, or film noir, I urge you to check out Crawl, you'll be glad you did!
Meat's meat, and man's gotta eat!!
