Given how many forum members follow the latest superhero movies, I wanted to float a question out there: which do you prefer? Cinematic universes or self contained trilogies (or a 4-5 movie series)? I am not talking about which makes studio's more money, I'm talking simply as a viewer and consumer, which do you prefer?
Since The Dark Knight Rises wrapped the Nolan trilogy, it seems studios are going all in on cinematic universes. But remember the days of superhero franchises that stuck to one hero, or team of heroes, and had a shelf life? Franchises had maybe 3-5 movies before being rebooted, and while there was universe building, it was contained to those few films. While Donner's Superman, Burton's Batman, and Raimi's Spider-Man started out strong and ended with disappointing third acts (or in the case of Batman and Superman, a fourth act), I'll admit to really liking easily digestible franchises like these over Marvel's current approach.
Not to say that Cinematic Universes don't have their positive points, but I do find it a bit of a drag that soon Iron Man, Captain America, Thor, and Hulk will be too old for the MCU and new heroes will be introduced to take their place. new takes on just about any of the Marvel properties in the MCU are unlikely for years to come, with MCU films planned as far as 2020. That's 12+ years of the same film continuity. And with such an investment in the MCU, a reboot would not be as easy as it was with Batman, Superman, or Spider-Man. Marvel has gotten better at making their films less samey, with Captain America Winter Soldier feeling like a very different film than Guardians of the Galaxy, but the MCU does have their basic template that they do like to stick to (I can't be to only one who saw GotG and thought it followed the first Avengers formula very closely).
Compare MCU's lifespan to Raimi's Spider-Man which lasted 6 years, Burton's Batman which lasted 8 years, Nolan's Batman which lasted 7 years and the original Superman franchise which lasted 9 years (I consider Superman Returns to be a light reboot of the franchise which was intended to be its own series). While these franchises (with the exception of Nolan's trilogy, IMO) had very weak final installments and were not made with the intent of ending when they did (with the exception of Nolan's trilogy), I think the fact that they did not rely on several other franchises in a cinematic universe AND that they told self contained stories with loose threads running from film to film worked to their advantage. Look at Sony killing Raimi's franchise after Spider-Man 3 compared to killing Webb's franchise after Amazing Spider-Man 2. Well Raimi very well could have made a Spider-Man 4 (and he planned to) the series works well enough as a trilogy and thanks to a universe building not being as prominent, there weren't many plot threads left hanging. The Amazing Spider-Man franchise, meanwhile, hinged on a Spider-Man cinematic universe with future film teases in place and several plots left unresolved.
My basic point is I think cinematic universes and self contained franchises both have their advantages and disadvantages, but Amazing Spider-Man showed us that the cinematic universe route can be a high risk for studios. Either you do it right, which I would say Marvel is doing despite me not being the biggest fan, or you don't do it at all.
Self contained franchises are far safer, easy to digest, and allow for new talent to tackle iconic franchises after 6-8 years. Burton's Batman and Donner's Superman went to some pretty stupid places, but they did have some fantastic first few movies and at least did not require 12+ years of existence, opening the door for new talent to reinvent the franchises.
