There are a lot of different ideas and I'm sure everyone of those will work great. As long as they have good writing, then I'm sure the audience will be receptive of them. Lately, it seems like they plotted everything and removed the flexibility of the film makers which is why I think the later movies feels so rigid. In the case of D&W, they mentioned that they approached the studio without even a finished script, and just made up everything along the way. Something that is parallel to the first Iron Man movie. This, I hope, will also launch another renaissance for the MCU. I guess Passion and Fan boy-ery is also a necessary trait to make a good Marvel movie.
