Regarding characters, I really like Poe, he has been my favorite character in the ST ever since TFA, and I’m glad he got developed even further in this movie.
Kylo Ren also gets a good share of character development, so he’s for sure second favorite.
Finn is not that interesting to me, and poor Rey in my eyes is nothing but a unrealistically overpowered character, which makes her boring.

I’m still not sure what to think about Luke’s arc in this movie though.

Too bad we lost DrDre, he was articulating a lot of what I think of the movie in more coherent ways.
