Drawn Together was full-throttle crudity and crassness, and this concluding movie makes for a satisfying ending. Although very much made on the cheap, with many segments of filler, the movie stays on par with the series, not adding much more or taking much away.
I laughed. In fact, I laughed quite a bit. It makes a nice little argument that "gross for gross' sake" is alright, and takes its time to critique South Park, the show that took its time slot. For the makers of Drawn Together, it seems absurd that a show can only be crude if its making some sort of commentary, crudeness by itself can be just as funny and not so pretentious as South Park. Many of those laughs were "bad laughs", the kind where you feel ashamed afterward. I find those good for my health now and then.
Technically, the movie lacks some of the hand-drawn aesthetic of the show, but the bar wasn't too high to begin with. This was never a serious show, great for when you just wanted to switch your brain off for a half-hour, and the movie provided the same dumb humor, and after three seasons I came to expect occasional lapses in the writing quality. Worth a look for a fan of the show.
