James Franco is just awful. He can't act at all and ruins everything he touches. Movie like This is The End are saved by a good supporting cast, where movies like Spring Breakers should get him shot.
Seth Rogan is just played out. His whole "I'm a fat, quirky Jew" shtick lost it's charm around Knocked Up, and now it's just irritating to see him play the same character over and over. His also a huge douche in real life and his non stop tweets make him look like a cry baby.
