Until the trailer comes out. I honestly think Avengers 2 should be the favorite to have the biggest opening weekend and to be the biggest box-office hit. It's Marvel, and their last two films this summer were great/really good. The only way BvS is going to make more money, is if they make a great film. When was the last time Snyder made a great film? Never, imo. SW has a strong fan base, but if the reviews aren't great, it's the prequels all over again. They will still make a lot of money, but Marvel really seems to know what they are doing and they have people's trust, which is something the other two do not have right now. People are curious about BvS and SW because they could be good or a total cluster****, but not Marvel. People expect it to be better or as good as the last one. That's guaranteed money.
