A sequel is an admission that you've been reduced to imitating yourself. - Don Marquis
There's an old saying that goes, "A copy of a copy isn't as good as the original." In Hollywood, the saying seems to go, "A copy of a copy could make more than the original!" It's nice to see that blow up in their faces when their half assed attempts at movie sequels don't pull in the bucks.
Of course there are the occasional exceptions(Godfather II, Dark Knight, Spiderman 2, etc.), as well as planned trilogies or adaptations of a series of books that seem to transcend the hate and box-office pitfalls. But let's face it, a majority of sequels lack the same spark, heart, and quite often effort(or over abundance there of) that the originals brought to the screen.
Here's a nice chart from DailyFill that displays sequels that bombed at the box-office, as well as their RottenTomatoes ratings.
