Vision is dead. I never said that he's smarter than Stark, Banner, or Strange. Idk how you came to that conclusion, because I haven't. Stark is also likely dead after Endgame, so...
Brie Larson is a divisive person. This is just a fact. It's not "internet trolls". There probably are trolls that don't like her. I'm not one of them. There's enough data out there for anyone and everyone to come to the same conclusion that she is not a likable person (awards have literally nothing to do with personality - it's about a particular performance). You can't pick and choose anyone else's opinions on a singular person. That's not how it works.
Tom Cruise and Scientology is definitely a good comparison for Larson...
