The one and only correct response to this thread is:
Oh my god, who the f*** cares?
People want a great movie first, action second.
Kids dig Batman more because of all the toys.
Are you insane Avengers is making more money!
People are tired of Thor, Hulk, Captain America...etc.
The last movie made more money than God so...
Since this is the last film people won't want to miss it.
