I don’t think that Marvel Comics, Captain America, Chris Evans or anyone else involved in Captain America movies should take offense if someone doesn’t like Captain America. Most likely, it is because they are adults who are not interested in comic book characters. Some adults are and a lot of kids are, but it is a matter of taste.
Some people especially adults have put aside their interests in comic book characters and like to watch movies like comedies and dramas and not sci-fi or fantasy. That just isn’t their thing. So, I think they would probably like Captain America if they were interested in those sort of things. Some people may have gotten tired of Captain America after seeing him in so many movies over the past decade.
