Batman>Superman he is a billionaire genius that is the point he would kill Superman because he would exploit his weaknesses. But Snyder did make the most recent Superman ridiculously powerful.
Also I have pretty much seen the entire movie in one trailer. Not looking forward really DC movies at all.
Now Captain America? Winter Soldier was really good. Not as good as Guardians of the Galaxy but still excellent. A lot of good movies coming out this year that is for sure.
