All of the wit and sophistication and in-jokes of the first film were thrown out the window, replaced by inconsistencies left and right, really weak jokes for jokes's sake and a tired retread of the plot of the first film. There's a really, really funny dick joke near the end of the film. Apparently, it was so funny, the filmmakers needed to repeat it, thereby making it not funny. You strain credulity far enough when you take all this religion crap seriously in a movie. Forgetting to write rules that bind the behavior of your characters, especially in films involving less than real conceits, is a disaster.

There aren't any old TV shows left to adapt. Unless you're going to play that element like Blazing Saddles , it just distracts unless the film is damn good. This one was damn awful. If you've seen the trailer, you've seen the film. That's another reason.
