To be honest? I think they're going to be fantastic. As much as people want to hate on Disney cause...they're Disney? The fact is they have amazing writer's, and all of their recent films have been extraordinarily good. Not to mention they got one of the best writers of Episode 5 on the team; better yet Lucas has no creative control what so ever. He's on as an 'adviser' but he wont be able to mess anything up.
There's just about no way this could go south.
Now don't jinx it!
I think it will be good. If Avengers did good, Star Wars VII will as well. I'm excited to see what they do.
