its funny, 'cause I take word for word almost the exact opposite view. The MCU is way more creative and allows for much more interesting stories because it has a decade of previous stories and character continuity in it. The next director to make a Spider Man story doesn't have to spend a third of their movie re-introducing Peter Parker, MJ, Uncle Ben and the spider bite, its already done. Tell something else.
Every MCU movie basically looks the same, feels the same, and goes the same direction. Each movie that isn't an
Avengers movie has the same placeholder villain that will pretty much not have mattered at all once the next movie arrives. Even the only really drastic thing to occur - the snap - was rendered pointless before it even happened since
Infinity War was announced as a two parter. And by the time
Endgame finished the snap might as well not have happened either. Every movie feels specifically designed to get to the next movie, and then the next one, and the next one. And nothing will actually change since these characters need to make money, and so can't actually have an ending.
This is why having comicbook movies exist within their own universe is important. Because it's pretty much the only way for these stories and these characters to end, even if it's simply because it's the end of that run. The end of the Sam Raimi
Spider-Man, the end of the Nolan
Batman. Eventhough Spider-Man is in the MCU now, and we're getting a new
Batman (because ofcourse) we don't see them as the same characters as they were in the earlier movies, because those were their own thing, they had their own identity, and directors who put their own stamp on it.
Meanwhile the DCEU is so adverse to quality, discipline and dedication every movie has to spend a huge amount of time re-establishing the characters, their personalities, back stories and motivations. And then it all falls apart because the next director wants to tell their version of the characters, so DC just says all previous movies don't count. Margot Robbie's Harley has had three entirely different interpretations over the last 3 movies, each functionally a separate universe version. Joel Kinnaman, who plays Rick Flag, said he was told absolutely play Flag as a completely different character, the last Suicide Squad movie doesn't count, and even though Flag dies in Suicide Squad 2, yes DC would just bring him back in the next one. Because they're so uncommitted to story telling and keeping track of basic things, it doesn't matter.
And to me that's the crux of the issue. The MCU does have a story they want to tell, and the DCEU doesn't. And I'd rather see Marvel have the characters they need to tell the stories they want, than it go the way of DC where everything is made up and the points don't matter.
For as bad as most of the DC movies are, I give them major props for being movies that feel like they're made by directors, and not a roadmap. As much as I think Zack Snyder blows as a filmmaker, it's good he's allowed to actually direct his movies. Whenever Marvel presents some famous new indie director for their next movie it means ziltch, because they're not allowed to even nudge anything that might slightly veer away from the path that has been planned 10 movies in advance.
