8. The Hangover
I am well-aware that the Hangover trilogy made a ton of money. I know it made superstars of its cast and director. I realize that it was and will continue to be considered a game-changer in terms of how comedy films are made and marketed. But all things must come to an end. I am always nervous when movie studios slap the "final entry" label on a franchise film in advance. That never actually means that this is the final one. It really means this is the last entry in this particular franchise until (a) it says otherwise, (b) it wants/needs money, (c) one of its previously participating actors/actresses blows up in a major way, (d) someone in a palatial office somewhere in LA decides a prequel, sequel, spinoff, or reboot is in order, or (e) all of the above. The temptation for Legendary Pictures and Warner Brothers to revisit the outlandish adventures of Phil, Stu, Alan, Doug, and Chow will be great in the next few years. But good people, the only real choice is none of the above, don't you see?
