Re: MCU: Phase II - Part 2
I think establishing the characters, making them well known since only Hulk was before, and then building to a team-up was the perfect way to go, for Marvel. But with DC, they already have Superman and Batman so Justice League would have asses in the seats right away, they can start off with the team-up and hook people on Wonder Woman, Green Lantern, and The Flash from there, then spin off.
But I'm sure as long as they put out a product people liked it'll be successful regardless.
