Man I've missed alot during my birthday bash
I'll say this, I think that:
1. Cap 3 could EASILY beat BVS
2. BVS could just as easily beat Cap 3
3. Both movies could end up doing roughly the same amount....
Honestly it's too early to say, though with the fact that Cap 2 was received better by critics than MOS, and with Avengers 2 probably driving the hype train...Cap 3 could be stronger than most people think. Also, Winter Soldier was more than just Cap. It had strong showings for Nick Fury and Black Widow, as well as a nice introduction to Falcon....
Cap 3 will most likely feature Falcon, probably more Black Widow and maybe even a heroic turn for Winter Soldier! So, don't let the title fool you, it wont be JUST Cap vs the big DC three.
I'm personally looking forward to both movies. Cap to see how they follow up an amazing sequel, and BVS to see if they can pull it off.
