This movie is going to be great, even die hard marvel fans should enjoy it because its not part of the world of DC and thus not directly competing against marvel. They wont feel like they are cheating on their brand by getting enjoyment from it. Some fans are die hard loyalists, they will hate anything from the other side, no matter if its good or not, much like politics. I dont think any hardcore marvel fan will associate this with the greater dc universe and therefore wont feel the need to attack it or defend their beloved properties. I could be wrong though.. i never could relate to those people, i get the best of both worlds cause i like all superhero **** marvel or dc. I am not a committed loyalist to either side, its all good pizza to me
