Perhaps Hollywood learned something from themselves when it comes to making sequels and turning good movies into franchises:
Have you seen Gremlins 2?
Or Ghostbusters 2?
Or the Karate Kid 3, not to mention "the next karate kid"
Or Police Academy 3-whenever they finally killed off that series.
The Naked Gun 2 & 33-1/3
That doesn't even mention other 80s franchises with terrible sequals (and often more than 1 sequel) like Revenge of the Nerds. Breakin, Nightmare on Elmstreet.
Beverly Hills Cop = Good, 2 was OK, 3 was forgettable
Coming to America while good, isn't exactly an original idea, how many "trading places" type movies have we seen thru the years? The 80s seems to have a million of them.
Die Hard, I guess you didn't know this was based upon a book:
At any rate, you confuse me, you complain that they make no new franchises, but also complain about the franchises on that list, 1 of which was made up from a ride at an amusement park, another from a toy/saturday morning cartoon (you're not stealing a story from that format). As far as I know, the Hangover, Kung Fu Panda, Cars and F&F were never books, so there are your 'original franchises' that you clamoring for, but complaining about at the same time.
