Most of the movie was ad lib, they've admitted it. These are not theater actors, they're film actors. They're not trained to be good at doing things "off the cuff." There WERE parts that were funny, but they were too few and far apart. The humor was sort of a slap in the face to my intelligence. I was more offended that I was expected to be entertained than I was the actual raunchy jokes. It was like a high school project with a really big budget.
Slap in the face #2. It was like watching a really long commercial. The characters actually fight over who gets to eat the milky way and describe why they love the product so much. Seriously? Aside from those things, there were a lot of little crappy plot devices that were way too forced. Why is Noah suddenly getting raped by Satan? Why does Franco's new multi million dollar concrete "fortress" home collapse within minutes catching fire, and why does it have a basement you can only access from outside? The overwhelming success of this movie in only its second week is proof that the standards of young movie goers is almost non existent. Better movies get drowned out because the industry is so over-saturated by crap like this, so in a sense, you can say that movies like this really are actually part of "the end."
