The remark "Do you want him to make a superhero or action movie or something?" implies that any desire for Anderson to evolve beyond his current style stems from a limited understanding of cinema, rather than a genuine wish for artistic expansion. Imo this rhetorical question can be seen as an attempt to dismiss the critique by framing it as unsophisticated. I found it a little condescending.
You are making assumptions about my intent and my feelings regarding superhero and action movies. I am not sure I would call most of Anderson's output particularly sophisticated and absolutely would not write off entire genres as unsophisticated, many dramas offer nothing more than an emotional appeal and many action movies offer considerably more.
