There is probably no movie franchise that knew when to quit ... on a high note.
To make for a solid franchise, I would say there would have to be at least 3 solid movies in it. I haven't seen all of the movies in the poll. But, from the movies in there that I HAVE seen, to the best of my recollection, for me, they pretty much all have only 2 solid installments.
Since Jaws isn't on there .... Just Kidding! :rofl2:
For the Poll, I'll give the edge to Star Wars because it had 2 first solid installments and then there in one of those later installments it introduced Cutie Natalie Portman.
I got a kick out of how that huge creature in the arena just happened to have slashed Natalie Portman's uniform Top very Sexily at an angle. :bowdown:
For a franchise that had 3 solid installments, I'd say Rocky.
After Rocky III, the franchise fell apart.
