Not a movie but a video game....
Final Fantasy. I mean how many are there now? 13-14. What part of Final do they not understand. To mean Final means no more after this one folks.
12, with #13 in development. Not including all the spin-offs.
But, here's some trivia for you. In the mid 1980's, Square had a string of simple games that weren't selling well and they were failing financially. Designer Hironobu Sakaguchi developed the original Final Fantasy as both his final project before retirement, and also the last chance for the company. It was a last ditch effort to save them from bankruptcy, hence the name Final Fantasy.
Luckily for them, it reversed their fortunes almost instantly and became the flagship series. Sakaguchi held off on retirement and stayed with the company until 2001. Instead of being their final hurrah, Final Fantasy became a juggernaut, particularly here in the U.S.
So now you know why the name doesn't make sense.
As for movies that shouldn't have sequels, Dragon Heart comes to mind. Sure the first wasn't the best, but I still like it, if only for nostalgia these days. Sean Connery is still the perfect dragon. But they completely ruined what charm the original had when they vomited up that horrendous sequel.
