The biggest complaint I've read about this movie is that it is "slow." While that adjective might accurately describe other movies, I don't think it's the right one for Crawl. Crawl is more "methodical," I would say, and only "slow" if it fails to hook you in right away. Anybody with any kind of movie savvy will pick up on the influence of the Coen Brothers and Hitchcock with this methodical style. Not a rip-off of their style, mind you - the influence. It's easy to say that the filmmakers just ripped off Psycho and Blood Simple, but I say that if it worked there, it's gotta work here. And boy, does it ever. Each frame and scene is painstakingly laid out with real directorial skill, and the suspense scenes will have you on that cliched edge of your seat.
The movie's less than exciting pace is made up for by some scenes of real brutality. The murder at the beginning is of course only the beginning, as the situation gets exponentially worse. Crawl turns out to be quite a bloody piece by the end - there's a car crash, a bludgeoning, and most deliciously, an axe put to awesome use. The makeup work is realistic and gory, but nothing over-exaggerated just for the sake of being gory. Not that I ever have a problem with that - it just wouldn't have worked for this movie.
Georgina Haig as Marilyn (whose full name we find out from the credits is Marilyn Burns... hahaha) is also perfect casting for this role. Her big doe eyes fill the screen, her innocence in this crazy situation heightened by her good-girl blonde hair and cute little dress. She isn't given much by way of character development but that didn't bother me too much here, because this felt more to me like a situational movie rather than a character-driven one.
Crawl is a movie deserving of every word of praise on its poster up there. It is a very successful slow-burn thriller that will hopefully have most movie fans salivating over the awesome that oozes out of it. Definitely keep your eyes out for this one.
