When it comes to movies based on Saturday Night Live sketches, you kind of take what you can get. I don't envy the folks who have to turn a 2-minute sketch into a full-length feature, and, as expected, most of the time the whole thing just falls flat. Since most sketches are built around one or two punchlines, once you deliver those in the first ten minutes of the movie, there's not much else to hang on to for the remaining hour and a half.
