Avengers: Endgame has the unadjusted all-time box office record. If you have seen Endgame, then you know storytelling isn’t a big deal.
Plot holes abound, yes, but the movies provided satisfying payoff for something like a dozen different character threads.
In a vacuum, Infinity War / Endgame aren't that great, but they were never meant to be seen in a vacuum. They're the culmination of hours and hours of building up characters that people enjoy.
Which character from a Zach Snyder film has any personality whatsoever? I can't think of one.
"This is SPARTA" is not personality. It's an aesthetic -- the image of a bearded musclebro kicking another musclebro into a pit.
That's the Zach Snyder experience, from what I've seen.
I say this as a person who watched and enjoyed Watchmen. Yet now that I'm watching the HBO Watchmen series I'm seeing just how joyless and devoid of insight or creative spark the Watchmen movie was.
Painstakingly recreating an existing work that is the product of creative inspiration is probably the best Snyder can be expected to do.
Probably my favorite superhero movies that I've seen recently are Thor: Ragnarok and the Antman movies.
A superhero flick should be a lighthearted thrill ride that is both fun and funny. They're called "comics," after all.
That's my perspective, anyway.
I read "The Killing Joke" recently. I can see why it was so influential. A lot of images that leave an impression. But would it make a particularly good movie? No, I don't think so.
