A dozen films in, the Marvel Cinematic Universe is a sprawling epic made out of what should have been a mess of movies, amazingly strung together regardless of the fact that none of these elements should logistically co-exist. While there was always a firm eye on the desired future of the franchise, the Marvel Studios films were obviously made on a case-by-case basis - and because of that there are a few obvious missteps along the way, which take away from the MCU being a cohesive whole. As Kevin Feige and the folks at Marvel began their 21st Century Bayeux tapestry of superheroics, there were a number of important lessons that could only be learnt along the way. Contract negotiations and the development of multiple sequels and new franchise offerings simultaneously are the kind of thing you get better at on the fly. The Marvel Studios of 2016 is going to be a much savvier animal than the Marvel Studios of 2008, that's for sure, and both fans and - surely - Feige himself can't help but look back over the Marvel oeuvre and notice what could be changed to make their Cinematic Universe a more cohesive beast. So with the expert use of 20/20 hindsight, what would Marvel want to change if they could go back?
