It's hard for me to like, or dislike, cinematic universes. It's the current business model du jour in Hollywood, and a way to generate an obscene amount of money. The MCU has been wildly successful financially, so others are starting to stick their toes in the water. That's Hollywood. Hell, that's capitalism.
At some point I have to believe audiences will become numb to the whole idea. The "inbetween" movies - the Iron Mans, Thors, and Captain Americas - are going to become less and less appealing since you don't absolutely have to see them in order to enjoy the tentpole releases like Avengers. That's going to be especially true the more Ant-Mans, Dr. Stranges, and Black Panthers we get. And those tentpole releases are going to diminish because they're all advertised as some kind of culmination or endgame, but they're really just placeholders until the next, bigger culminating film. I mean, the MCU has only gone through this cycle twice and the complaints about homogenization, boredom, and never-endingness are already pretty loud. Maybe Star Wars, or DC, or someone else, does it better and masters it, but it feels like an unsustainable long-term business strategy. Not that studios care if they can use it to make a gazillion dollars in a decade or so.
The thing about the MCU that bums me out is now that we're getting to the point where the lesser known superheroes are getting their own movies, they're still content to stick to their formula instead of risking losing some control to make something quirkier or more interesting. The whole Edgar Wright/Ant-Man debacle is as eye-opening as it is puzzling. They seemingly hired the perfect guy for the film, and then clashed over what that film would be like. You hired the right guy for the job, why not trust him to do that job? Especially on something like Ant-Man. These feel like the movies where you can take chances and give an autuer-y director like Wright a bit more freedom. Maybe that comes with a reduced budget to minimize the risk. But no, Ant-Man is a $140 million dollar movie that looks a lot like everything else Marvel has released (full disclosure: I haven't seen it).
Star Wars has hired a bunch of interesting directors in addition to JJ Abrams - Rian Johnson, Gareth Edwards, and the Lord-Miller duo - but how much control are they going to have over the movies they're directing? If Looper, or Godzilla, or 21 Jump Street fails, that's just one bad movie a studio has invested in. If a Star Wars movie fails? There's more than just the individual movie at stake, yet the directors are likely only going to be around for their one movie. It sounds like a recipe for more studio control, not less. And that's probably my biggest gripe with the idea of CUs, at least with how Marvel has implemented the idea - they suppress creativity because they're a business model, not a creative enterprise.
