I think we're having a cycle of spoof films right now. To some extent we're still having the cycle of comic book films, a cycle of romantic comedies, a cycle of war historical films, and fantasy type films. I never thought we'd really have an spoof franchise that comes out every year or so.
Although I do believe Superhero Movie has potential. But we'll never see great spoof films like Airplane, Spaceballs, Hot Shots, Naked Gun, or Blazing Saddle again because those were intelligent spoofs and were actually funny.
Scary Movie 1 is, in my opinion, the best spoof film of the 2000's really.
