Yes, but I'm specifically talking about fans who WANT those movies. There are quite a bit that find the movies speak for themselves with no sequel, prequel, or whatever. There are a lot of them that just ignore new films because they already feel it just won't be the same.
I mean the ones that get super duper excited about something and have high hopes to whatever fan fic idea the movie's going to have and be completely disappointed by them.
That said, the WORST ones are from franchises that aren't controlled by the same directors and writers. And the worst of the worst are sequels where in the original concept, be it a book or a comic book or whatever and they completely ignore it to make something kiddy and terrible. I'm looking at YOU, Son of the Mask, Jungle Book 2.
