How can Ren even still be alive? Snoke says "Bring him to me" yet he's lying half dead way out in the woods. Rey jumps on the Falcon and five seconds later the whole planet blows up. How did they have time to find Kylo and get him off the base? Seems like they should have put in a shot, for just a second or two, of Rey looking back and seeing that he was gone or something.
Another thing: When Finn and Rey are escaping Jakku, the Falcon is whizzing around doing flips and turning upside down and all. Neither Finn or Rey are strapped in, why aren't they flying out of their seats? You say the Falcon has it's own gravity? Okay, fair enough, but if that is the case why is BB8 getting thrown all up the walls and onto the ceiling?
Oh wait, I forgot, this is just a movie. Never mind......
