I was really hoping that Hulk would be MCU but I think the look they've went for is timeless and will be a superior choice in about 10 years. A lot of comic book films haven't aged well and I think in about 10/15 years, MCU will look dated too while MSHI will still look as good.
I'm even more interested now to see what they do with Avengers if they build a ride but given the comic style, I don't know if AAs will be more or less likely.
