Yeah, I would say I “prefer” the DC movies, or at least I prefer their approach if not always the results, and it is simple storytelling preferences I think as you mention here. DC includes little details (like the horses in BvS) that I find engaging, and acknowledges humans a bit more, which I find engaging. They grapple with superheroes as myths and folklore which I enjoy.
And I agree with you completely here. Personally I don’t think I’ve ever laughed during a non-Guardians Marvel film, and I find their jokes really insipid, such as the example you provided. And there are countless others just like it. I should preface this by saying I never liked Wash in Firefly and now most of the Marvel characters are interchangeably written in Wash’s voice.
I would love to see a Marvel movie where the material, and really the superhero genre in general, is treated more seriously. I really liked Black Panther for this reason, even if there were a handful of jokes it was kept fairly light.
It’s a stray thought but I wondered recently if all the Whedonesque jokes in Marvel, Star Wars, and the animated movies have killed the comedy genre somewhat. Why go see a comedy when the action movies all have jokes? It feels like a long time since we’ve gotten really iconic comedy movies that have captured the public’s imagination the way stuff like Anchorman or Borat once did. Maybe Bridesmaids was the last one. It’s still popular on TV, but movies not so much.
