> The Star Wars sequel series (episodes 7, 8, 9) come to mind. I think the majority of complaints came about because they dared to do something new to Star Wars.
My takes:
VII — Lame soft-reboot story, typical so-lazy-that-it's-bad JJ plotting. Bad, but not so bad it's not salvageable if the next two are good.
VIII — Oh thank god, easily the best Star Wars movie since the original trilogy, might even be better than Jedi—oh, wait, everyone hates it? WTF?
IX — One of the biggest train wrecks of a movie I've ever seen with a budget anywhere near this large. Fascinatingly bad. I was quite entertained, but not because it was good. It was like a 7-year-old who loooooved the original trilogy wrote their own sequel, complete with messed-up pacing, nonsense plot beats, confusing geography, a bunch of stuff that goes nowhere, and bizarre mash-up action. It was a fun watch in a "laughing at it, not with it" sort of way, but a really bad movie.
"Doing new stuff" wasn't the problem. Biggest problem overall was probably that JJ shouldn't be allowed anywhere near a plot, ever. He can punch up dialog (if we must do the modern "quips, quips as far as you can see in every direction" writing, anyway, which apparently we do), direct, and definitely do casting. No touching the plot.
On the plus side, only one of them's bad enough that it should be ranked down with the prequel trilogy. But another's not very good, and the other's the middle entry, so hard to recommend when the other two aren't good.
