It's an age old complaint that Hollywood has run out of ideas and is just producing remakes and sequels, but it does really feel like now franchises are almost expected when first starting any reasonably big production. And it's definitely a franchise, rather than just a sequel or two based on good box office receipts. Recently we've had (off the top of my head, so there's bound to be more): 6 x Fast and Furious 4 x Bourne 8 x American Pie (I think there's a good argument to consider it this generation's Carry On) 4 x Pirates of the Caribbean 4 x Terminator, with a 5th apparently on its way All the superhero films which show no signs of stopping, including 4 x Spiderman, 3 x Batman, 3 x Iron Man, and the Avengers series. Any more for any more? I haven't included horrors in the above list as they've always had a tradition of producing a series of films.
