I recently watched Spider-Man Brand New Day, and BOY do I have some thoughts, especially regarding Jean Grey.
So, the film after the third act tries to portray her as a victim, making her out to be a character the audience should feel sympathy for. However, I really don't think she deserve said sympathy. She has actively endangered and even killed people without a second thought and has done some pretty awful things throughout the movie's runtime. "You're not a killer" says Peter Parker. AHEM! *points to the scene where she gets some random guy ran over by a car, gets The Punisher to shoot those two Damage Control guards and drops MJ off the side of a building*
I get they were trying to make a morally grey character, but having a character do awful, unforgivable acts and then telling the audience they should feel sorry for them doesn't make them morally grey. It just makes them evil, but with a tragic backstory.
She didn't deserve to be let off scott-free at the end of the film. She should've been put into prison or something.
