I actually liked Kylo Ren as the villain because he wasn't as badass and self-confident yet. He was still torn and drawn to the light side. I think he was supposed to seem kind of immature and insecure.
Yeah I thought that was interesting as well. Usually we've seen characters struggling against the dark side within them, but here was someone who was struggling and uncomfortable with the light side, and acting as if
that was the cancer eating away at him and preventing him from fulfilling his destiny.
This is also something that really appealed to me. I think that one of the goals of the prequels was to have us feel sympathy and pity for Anakin as we saw his path to the dark side. However, due to writing, the actor, whatever reasons you want to give, it didn't happen that way. Anakin didn't seem like a very sympathetic character and rather than feel bad about his turn to the dark side, I just saw him as a whiny brat and didn't care much what happened to him.
However, Kylo Ren seems to be following a similar path now, except flipped - struggling with the light side rather than the dark side. And I think it is easier to feel some sympathy for him. As others have mentioned, he has grown up overshadowed by these greats and clearly has a struggle with self worth. Am I upset he killed Han? Of course, but I also do feel genuine pity for Kylo Ren. He is a whiny brat as well, but he pulls it off in a way that makes you feel a bit sorry for him and like you hope he can find a way to work through his pain and anger and overcome.
Give me bad ass Sith Lords any day. I just felt all the bad guys in this film were lesser versions of what we've had before. It is different and on some level I look at Ren and think it is interesting that they went that route. He just isn't intimidating anymore though. I want a villain that at first overmatches the hero, that presents a credible threat, and allows suspension of disbelief that the hero might not or won't survive fighting them. Ren started out that way but then crumpled. Now I'm less excited to see his second encounter with Rey. Of course I'll be watching it, and all of the Star Wars films-for the foreseeable future until they pile so many on that even I can't take it. However I have a high tolerance for pain where Star Wars is concerned.
I think they are going the opposite route with these films - rather than start out with this big, scary, overpowering evil thing that we aren't sure our heroes can destroy, the story seemed to focus more on how powerful and strong our new heroes are. Even the most inexperienced among them (Rey) is totally badass. She is the one who is intimidating. Instead, it's the villains that we aren't sure will get it together and defeat the good guys. The villains are unsure, amateur, conflicted. I find this a very interesting twist. It's almost like we want the next movie to show us that Kylo Ren can actually do it, can actually pull off evil, whereas in the first trilogy we were hoping the opposite with Luke.
One reason I like it is because I genuinely don't know where the story is going to go. When you start out with a big bad evil character and underdog villains, generally you can assume that they will train, be tested, find a way to overcome, etc. It's more predictable and we've already seen it done many times, and done best by the original Star Wars trilogy. No need to do that again. Even though there were many parallels between this movie and the first Star Wars, I am glad to see the story flipped a bit. As I mentioned above, it's like what we wanted to see from the prequels but never got, but even better because we don't know how this story will end.
