He is self-deprecating but both of them obviously firmly believe that they’re right and everyone else is stupid and wrong. They frequently attribute the success of movies they don’t like to audiences being stupid or simpletons (see their Rogue One and IT reviews). No matter how ‘common folk’ they seem, that’s their obvious perspective. Like I said, I do the same thing but I don’t pretend otherwise.
They pretend otherwise? I think they’re pretty blatant about thinking they’re right. Yet I don’t see the problem with that. I think you’re taking them way too seriously.
