The movie was a disappointment. i thought it was going to be about them leaving earth on a spaceship and somehow accidentally going through some kind of time travel loophole and ended up back on earth 65 million years ago. but no, it was nothing like that, in the movie they literally just crash land, shoot at dinosaurs, find the escape pod and barely make it out. Also, we don't even know if they make it back home or what. it was a big disappointment.
