But First Class was done in a different timeline, so it was the same Eric and Xavier, but they were much younger. It acted as a prequel. That's not the same thing. We aren't pretending that Logan saw completely different characters (aside from how they changed Sabertooth from X-Men to Wolverine Origins, which was weird). After that, they specifically used a time travel movie to allow the continuity to change. That would be akin to a Flashpoint movie. But if we are getting the same Diana and Barry and Arthur, etc, but there is no explanation as to what's happened with Superman, that's pretty strange to me, imo. And even if they do eventually have a way to explain Superman's presence in the future, the fact is, as of now, I have no faith in WB right now and have no idea what they are going to do, so it's hard for me to personally care.
