Like Liam H said, Marvel never needed Thor to be a huge blockbuster hit. They probably would of been happy with 350 million WW.
Instead they got a pretty good hit, a character that not many knew of(Marvel wise) which is now known for future sequels and The Avengers and a movie that was very well received by all. Marvel made a pretty penny over Thor.
Fox unfortunately didn't have a huge hit with First Class, the upside is that the film was very very good and very well received by fans and critics. Though it didn't have a major characters or stars the other films had to attract non-fans to it. Overall though it will make some money. I think the 160 million budget though was a bit too much, Fox should of went with 140 or something around there.
I think most expect that WB wants to do what Marvel did with their superhero films. The difference is that Iron Man, Iron Man 2 and Thor were good to amazing films, with great acting, good stories etc. Green Lantern was a mess with shoddy acting and bad marketing, of course it had it's bright spots but it wasn't a very good film at all.
WB needs to go back to the drawing board, I don't think we'll get Wonder Woman, Flash, Aquaman or Justice League anytime soon. I do believe that GL's failure has catapulted a Worlds Finest movie into WB's plans.
