Didn't think it'd get reviews like this but I'm sure it'll still make a good chunk of change. They've already announced a sequel.
Superman Returns was supposed to have a sequel too called "Man of Steel" but Time Warner didn't like the Luke warm response the movie received and opted not to go that route with the Superman Franchise. Most blockbuster movie contracts are usually 3 film deals. If the films are successful then the studio will option to do another one; if not they will dead it with the quickness like Superman Returns and After Earth etc.
Anyway the bad reviews and press don't mean nothing to me I am still going to see the movie and make my own judgment. Most of the movies I like usually get bad reviews, lol.
