To be perfectly honest, I don't really care about Captian Marvel one way or the other, I will probably see it or rent it( if it is out) before avengers 4, but all in all it's a pretty big meh. Not one of my favorite characters, and the lead actor seems like her heart is in the right place, but is kind of a doof.
What I am really excited about is this opens the door, some what*, to a Ms. Marvel movie.
* you kind of need the Inhumans for the terrigan mist thing, and Inhumans went poorly, but you could change the origin of her powers to anything really, and AoS is kinda already dealing with Inhumans, but I hope she gets a movie and doesn't end up a a one arc character on the TV show.
