The first half is kinda promising, but then the main character's development just STOPS. Lmao?

It's late and I don't really want to think of marvel, but for some reason I am doing this anyways. So ok, when I saw this movie first (in the cinema), I thought it was amazing and the best Marvel movie ever (= possible 3-star ranking), but I changed my mind when I watched it a second time. By the end of this 2-and-a-half hours "ride" I wished they'd JUST STOPPED FIGHTING! You see, I was bored to death by the never-ending action.

Standart Marvel: No real characters, everything mid. Nothing interesting going on here.

I know that an awful lot of people gave this movie a mid rating, but hey, other then you thought it was boring: Is there really anything bad about this movie? Anything? (tell me and I'll change my rating. Except I will not but I would be interested to hear your opinion anyways)

Also, this movie somehow feels like reading Japanese literature. Another reason for me to give it a high score.
