Query: Unnecessarily crude and vulgar.

The relationships between these characters is so violent and dysfunctional that it makes the movie completely unbelievable. Add to it the gratuitous amount of cursing, bad writing and a terrible premise and this movie was completely unwatchable.I can appreciate crude humor from time to time. However, this movie was nothing but crude humor, at its worst. There are really NO redeeming qualities to this film.I rented this from Block Buster, expecting it to be good. I heard generally positive reviews and never heard any complaints. My girlfriend and I took it home and watched part of it. Got about 45 mins into it and shut it down. There was absolutely no point to watching anymore.
