Starting by saying, I haven’t seen this movie so this is an outsiders opinion.

This appears to be completely different than your standard super hero fatigue. Some movies are just bad.

That said, the Groots things you’re expressing aren’t new. Action movies have always had dumb plots filmed with one liners all over. The feelings you’re expressing is that Super Hero movies are just also action movies. Personally, I find them more engaging and entertaining than non-super hero action movies specifically because they aren’t trying to be realistic but also have a continuity that I enjoy. That’s not a general populace thing. That’s a specific reason I enjoy them.

The minions complaint is just super weird, though. Those movies are tailored to kids. Literally zero adults should be taking them as more than a kids movie.
