That's awesome. I've never seen any of those movies, don't really go to the movies very often, but I think it's cool people react that way.
People getting upset about it need to relax. It's an action movie of super heroes fighting super villains, if someone gets excited during an entrance of their favorite hero, in a scene that is insanely loud to begin with, big deal. When I go to the movies, I don't usually cry, get excited, laugh hysterically or show a lot of emotion it's just not me, but if other people do then let them enjoy it. If it bothers me if people cry at a sad movie or cheer during an action movie, I can watch the movie at home or at any other time when there aren't likely to be a lot of people in the theatre.
This is a community where people stood up and hollared and lost their hats at a fucking E3 tech conference when a company unveiled that they'd be releasing a sequel to Shenmue someday. But, apparently, getting excited when the THOR GOD OF THUNDER appears in a movie called GUARDIANS OF THE GALAXY is bad form. I didn't stand up and scream when shenmue 3 got unveiled, but other people did, and whatever, if that's how they want to enjoy a tech conference, who am I to yuck on someone else's yum.
Also, different cultures are different. The take that someone else's culture offends you because they're different from your own is an ignorant take. What might be acceptable somewhere might not be acceptable somewhere else, and vice versa, you don't have to be a cultural supremacist just because something isn't common where you're from but might be common elsewhere or among different people.
