Re: *Spoilers* Problems caused by the MCU
^Yes there have. Favreau even said so. But even more than that there was a set goal to start out small/more grounded and gradually get more comic book fantastical. Favs said that as well. Where as Nolan pretty much kept it all in line throughout his films and chose not to expand, the Iron Man franchise had a different goal all along. I would argue that Nolan after BB could have done the same as well, had he chosen to do so.
Currently enduring a general malaise at the quality of live action Marvel/DC shows on network TV. Hopefully NetFlix can remedy that.
