I've never watched the other movies, but I know the deal OK. But I watched this one because of the hype. Was fun and everything. And kitten now I have a crush on Poe and his actor, ahg I didn't need this..
I think Rey is more OP than a Mary Sue. She has some complexity, I think female characters gets branded a MS so much easier than men. Maybe Kylo Ren was defeated because they're not planning to make a sequel? IDK. They should, if they like money. Maybe he takes a Zuko.
Rey's mind control was kinda cool actually, but I didn't like how she suddenly became a swordmaster after refusing to fall off a cliff.. Her knowledge on those machines made absolute sense, but they pushed it too much with the constant compliments from Han. I think Finn is cute, but I've seen his character in so many other movies, he is nothing new. I think my fav character is Rey, Poe, and Maz.
My biggest complaint was Han Solo's death, I mean wtf? Is that how he really died? I expected more than that from such a big character, and Wikipedia showed an entirely different ending for him.
