Saw it for the second time today, and it was better the second time. Things I missed because of the excitement first time I caught. People are still missing that Rey had training before being abandoned, whether Keg calls me a dickhole or not. There are multiple times in this movie that it is implied or straight up put in your face that Rey was one of Luke's students. Yet people are saying she magically picked up force abilities. It sprinkled throughout this thread. During Kylo's interrogation of her, I'm pretty certain that by the end he recognizes who she is from before the massacre of Luke's students. The awakening was within her is the entire point.
I see a lot of people talking about how there was a lot of things unanswered or uncertain in this movie. As someone who saw all the originals in the theater as a kid, with three years in between movies, some of my fondest memories growing up were the talks I would have with my friends about "what do you think...". One of the biggest issues with the prequels to me was that Lucas spelled absolutely fucking everything out explicitly, and answered every question he could think of (where did Boba Fett come from...fuck I was happier not knowing). I've already had more in depth conversations with my friends and my nephews about what we think is happening moving forward from this movie that I ever did with my friends after any of the prequels.
The old gen Ties didn't have any protection. Finn and Poe stole a Tie Elite next gen Tie Fighter. The ones with the red arm leading to the left wing. They have gunner seats, some shielding although very little, and limited hyperspace capability. Just nerd stuff, but true.
