Maybe I'm a bit jaded from watching a large amount of movies but I thought it was boring. Completely uninteresting characters which made the action a bit pointless.
Hollywood is an American export so you're gonna have American heroes saving the world. Do foreigners complain that Indian movies only have Indian heroes saving the world? Maybe. I don't know.
It's a silly criticism. This is different that the Mighty Whitey trope which is a problem is Western cinema.
I'm probably gonna have stuff thrown at me for this, but if I may contrast Pacific Rim with my all time favorite disaster movie, Independence Day.
ID4 had characters which I cared about. They were stereotypes, sure, but that had defined personalities with funny quirks. They had families whom you followed throughout the movie and in whom you invested emotion.
None of that in Pacific Rim. All flat, one dimensional character. The worst of which were the scientists.
I don't know. I'm of mind that action without emotional investment in the characters is pointless and boring. I can't be entertained by pretty CGI anymore.
On a positive note, here's the funniest trailer for ID4 I've ever seen:
