There you are being all reductive, and snobby. Of course pop music can be high art.
But really that’s besides the point. There TON of simple great art. Look at Die Hard, generally considered to be the most technically perfect action movie ever. And you can’t get more simple.
Yes you specific reason for DISLIKING Nolan. None of which show they aren’t GREAT movies. You just don’t like them.
Snobbery is the chastity of the perfectionist. Anyway, as far as action films go, I would take The Warriors over ‘Die Hard’ any day. Not to mention ‘The Road Warrior’. But I like John McTiernan in general - he really knows how to compose for the wide screen really well. His remake of ‘The Thomas Crown Affair’ is beautifully shot and beats the hell out of the original. And no I don’t regard any of those films as great art. The question of whether or not film can even be great art is not at all settled. I’m not sure actually. But that’s a separate issue.
