Hahaha i felt the same. MCU just made these series of movies really well, I didn't think it was possible. I remember more than 5 years back, talking to my non-marvel knowing friends how epic it would be to have the infinity war in the big screen but I don't think it was possible to make it epic. I always felt that Marvel is underappreciated (the x men movies are dogshit) and i'm super happy to see their genius being appreciated.
Agree again with the casting. When I was watching Ragnarok, I was telling the wifey how awesome Blanchett is for the role. I also was watching an interview with Hiddleston and was surprised how popular he was with the fans:
FYI a friend of mine named her son Loki because she's a super fan..

I'm amazed how Marvel can even make villains become superstars (i.e. Thanos) and DC can't even make their super heroes lovable. I lol'd at the Loki comic con entrance, where he makes a surprise appearance, insults the people and he still gets so much cheers.
