The general audience loves this franchise, critics may have not liked the sequels, but most people did, they were fun action-adventure movies with dinosaurs that looked practically real. And we don't get many dinosaur movies anymore, except if you go on SyFy and find a terrible B-movie. Now, they've moved on with people going back to the island because it would make no sense to have characters return to the island after 3 times of bad shit going down. We now have an open park, something we never saw, we have these dinosaurs in control, something we never saw before, but of course, something has to go wrong. Sure it isn't breaking into new ground but honestly it's 2014, stories aren't original anymore, it's about how it's portrayed on screen whether it be with great characters, good acting, some emotional or tense material, or hell just a good popcorn flick. The point of these movies is people try to think they can control life and they learn they can't, humans never learn, all of these movies have this theme.
so maybe each sequel was a rehash of the original , but they weren't terrible movies for it, and I don't think this one will be either. It has a good director, a good cast, and a good production team. And it has friggin dinosaurs! so I'm in.
