I loved it. Piranha 3D is what Snakes on a Plane wishes it could have been. It's not just exactly the shameless schlockfest I thought it would be, it goes way, way beyond it. Depraved, gross, disgusting, bloody kills, and so much boobs and ass it's basically a porno movie. Absolutely shameless, especially for a mainstream Hollywood movie. This is not a movie that can be discussed in polite society. But here, I'll say for the interested and like minded, it's fucking great.
The shrimp joke was going a long way for a punchline that was...eh. The self-referential jokes about the cutaways was probably the best part of the episode. I thought the plot had promise, but they didn't really follow through.
