I do want to point out that "legitimate artistry" doesn't equal "deep thought 100% philosophical" all the time or even most of the time.

Like I think Indiana Jones is legitimate artistry. Same with The Terminator. Or Alien. Or Mad Max. Even Sinners is legitimate artistry. Get Out.

I haven't seen it yet, but I get the impression that "The Odyssey" was made because Nolan thought the subject matter was interesting.

People have made cool movies for the love of the game forever. I think the big difference is "did an executive come up with this idea in a boardroom?" Or "did a real creative person come up with this idea?"
