This is the only actual good critique in the thread. However I’d add that they make clear that he was a communist-sympathizer. He betrays them however, morally speaking.

It also seems a bit reductive. These are legit points to make but they do strike me (and forgive me if this is not the case) as a very American thing were people judge a film based on whether particular ‘cool’ or ‘important’ things happened, whereas movies as an art-form and not just entertainment, and beyond highlighting everything political which we would like them to, can also use formal visual and musical language to convey other themes and ideas. I’d say the film has some clear strenghts in terms of the latter while agreeing with you that it has some clear weaknesses in terms of the former.
