First, I'm a big Adam Driver fan. Hard to imagine what he thought when he read the screenplay. So many plot holes! First, the premise: People on another planet, 65 million years ago, look just like Americans, on a planet identical to earth! And the same atmosphere. Same gravity. What are the chances?! And they speak English!! Here's another doozy - a T-Rex has me trapped in a cave. I know! Let's chip our way out the other side instead of waiting for the giant hungry reptile to go and eat any of the other bazillion big lizards running around the planet, apparently in that particular area! Uh oh, cave in. I guess I WILL go out the front door. And T-Rex conveniently flips the crashed rocket ship pointy side up, flamey side down, after it falls off a cliff. Thank God the rocket still works perfectly! And all 5 seconds before the meteorite that destroys the atmosphere! You get the picture . . .
