It was somewhat touching to see all the characters age I can agree. That moment when Chewie got pissed off was powerful and sad.
I have to say that I am kind of dissapointed with the Stormtroopers. I understand that 20 years ago there were different standards of acting, so I have no problem with those troopers running around aimlessly, in no formation whatsoever, shooting like a bunch of babies with their diapers on. But come on, these Stormtroopers were much better, but still dissapointing for me. Although if they wanted to still retain the old Star Wars feel, then that's perfectly understandable.
Apart from some of the cheesy lines and acting from eg. Finn whose comments were annoying and juvenile I'd say it was a pretty interesting and entertaining movie. I would of liked to see more of Phasma, especially that they potrayed her as a "badass looking trooper in silver armour".
Kylo Rens looked like a emo teenager with a duck mask, but what I absolutely loved was when he described what the dark side of the force was doing with him internally. Also the fact that he killed his father just shows how the corruption in him has spread. Comparing him to Darth Vader, I would say that he excels in his downfall because Anakin was unable to kill Luke.
Also that BB unit was fucking sweet and it was fantastic to see C3-PO and R2-D2 again.
