That's not a great header for what I intend, but here's what I want to hear: series of movies in which each entry was worse than the prior one. I thought of this when I saw mention of Lethal Weapon 4 elsewhere. I think that there's a drop-off from each film to the next: LW2 is noticeably worse than the original, LW3 is worse than 2, and LW4 is worse than 3. I'd also pick the Godfather series. 2 is excellent, but it's not as good as the first flick, and 3 marks a big drop. I'd NOT pick either the Alien or Terminator series. I like Aliens and T2 best in those. Jaws would probably work. 2 is clearly inferior to the original, and 3 drops even more. Is 4 worse than 3? Probably, but both are so bad this may be nitpicking. What other series would folks nominate? Ground rules: the series needs at least three movies to qualify - if there's only one sequel, it's not enough. Lets' hear some choices!
