Re: *Spoilers* Problems caused by the MCU
I think an element of all this is that over the course of many years they have been trying to condition audiences to accept things more like comic book readers do. They're still not quite there but audiences have definitely come a long way in what they'll accept from the leather-clad X-Men of 2000.
Currently enduring a general malaise at the quality of live action Marvel/DC shows on network TV. Hopefully NetFlix can remedy that.
