The answer on the quality: We have no idea.
But if I were to guess:
1.) Avengers 2 will be up to our expectations..
2.) Star Wars 7 will able to capture the magic of the originals, making it a SW sequel that brings back the ones who were indifferent towards the prequels.
3.)Batman/Superman is the wild card. It's up to Goyer and Synder.
First of all, I definitely think that these 3 movies are
THE 3 movies of 2015, no question. Those 3 are battling it out - every other movie is watching from the sidelines.
In my opinion, Batman/Superman has the most to gain, and can potentially be the most successful AS LONG AS Snyder and Goyer deliver something amazing. Plus, it's different and fresh.
And it's never happened before.
Avengers 2 sort of has to "prove itself" in a way, because not only does it run the danger of being more of the same, but in all actuality, it will be. It will be great, no doubt, but will it be a game changer? Will it have that X factor? Probably not. Superman/Batman is changing the game, if only because (if I may wear my heart on my sleeve for a moment...) Batman and Superman are the two greatest, most iconic, and
first superheroes ever. This isn't Hulk and Thor - this is big, BIG leagues. The biggest. Only Spider-Man follows behind them.
Episode VII is a big gamble, in my eyes. Abrams isn't exactly amazing or edgy, there will probably be lens flare, and Star Wars fans are THE most unforgiving, rabid, clawing, vicious, passionate fans in the world. If
one thing goes wrong or is disliked in this film, it will be torn to shreds. It hasn't even begun filming yet, and it is
already on thin ice by my estimation. If they kill Luke, if they add Zac Efron, if they do ANYTHING, they
better know what they're doing, because there will be an all-out assault. I'm a huuuuge Star Wars fan, and I'm just going to sit this out patiently until I feel comfortable saying, "I'm excited for this movie."
So yeah, Superman/Batman for the win.
