The movie was pretty funny. The only problem with it, though.. Is that it seemed to be a 'hybrid' movie--half of the movie was off the wall, random nonsense like the show, and the other half was the actual movie's "plot." The problem was that the random part was good, but the plot, while interesting, wasn't funny.
I'll be vague so as not to spoil for anyone who hasn't seen it yet (but if you haven't, why are you reading this thread?) but I didn't want to see how much of a loser the 'older' one was. Even if the movie was about correcting the future, making sure he didn't exist--the initial "real" future where "You will bow to me!" would've been funnier for a movie.
