Wait, the name of Chris Pratt's character was OWEN?! Good Lord, no wonder nobody could remember his name and just kept calling him Chris Pratt's character (or Smelly Twat, if they wanted to amuse themselves with some rhyming).
Alright, speaking as someone who found J-World to be an awful patchwork farce and figures this is going to be pretty much the same, I'm going to pitch an ending to the film, and I guarantee that it will better than whatever will actually happen (or will be more interesting, at any rate):
Claire finally has enough of being criticized for just existing and decides to ally herself with the dinosaurs in taking over the world. She climbs atop the T-Rex and orders the raptors to devour/rape Smelly Twat alive in a manner akin to what the MP-Evas did to Asuka in EoE. The island, now powered by the magical vengeance that allows Claire to command the dinosaurs, lifts off and travels around the world. Claire and the dinosaurs proceed to take over the world to the while
Rime of the Ancient Mariner plays in the background, with many scenes of the characters being brutally torn apart. The dumb children and their awful parents are rammed by a Pachycephalosaurus, and Jimmy Fallon dies the same way that the babysitter from J-World died, because fuck him. And, in a move that may or may not go down well, the dinosaurs break out of the film and tear the audience of the movie theater to pieces. Their conquest of the world has begun.
