Movie Sequels that Bombed... Is your favorite on the list???

Sequels often fall victim of the economic concept of The Law of Diminishing Marginal Utility.  This suggests that as we "consume" an additional unit of the movie franchise (fancy way of saying the sequel) that we, perhaps, get less satisfaction relative to the first movie.  Our satisfaction may still be positive but is decreasing as we consume the sequel.  One example of a sequel that actually maintains utility (satisfaction relative to the first) would  PERHAPS be the Rocky franchise. The first was great, the second, bleh, but how about the subsequent ones??  DEFINITELY have to say they reach negative utility affter IV? V?...Can you think of a movie and it sequels that kept up your utility overall?? :)  From (Chartporn)
