My main problem was the Fin character. For all the hubbub that was made over having a black lead, I thought his character was very poorly written. Why make him the comedy relief to such an extent? Maybe they will improve the writing for his character in the next film.
You waited over a year to see it? I admire your resistance.
I especially agree about Phasma. I don't know what I expected from her, but I certainly expected her to do more than stand around looking shiny.
I like the fan theory that Phasma is a alliance sympathiser or double agent and lets Finn escape.
The whole thing about Rey being overpowered really only becomes an issue when she's compared to Finn in any way. She's written to be sooo amazing and he's written to be sooo pathetic, there was no balance between them at all.
