I presume that you know, that the reason why Nolan's/Bale's version of Batman was "weak" is because that universe was grounded in reality. That has nothing to do with Bale's performance but rather the script and universe they were building. I personally prefer seeing Batman as a HUMAN, a stealthy detective, that has to be smart and selective in order to take people out. Snyder's/Affleck's version of Batman has to stand toe to toe with Superman and his army, so of cause he is going to be up-scaled in terms of power, basically turning into a superhuman. Who needs stealth and brains when you can dodge lasers that travel at the speed of light? And in the same universe I have to buy the fact that no one can see the the resemblance between Clark Kent and Superman(who is on news 24/7). I guess it only makes sense, that people won't notice a 1.92 m. tall guy in a gray costume jumping off the rooftops. Basically I feel like BvS is going to be a great comic book movie(I mean it's Batman and Superman) but I am very uncertain it will be a great, cohesive movie that can stand toe to toe with great movies in general(Like The Dark Knight actually managed to do). With that said, I am excited to see Batman and Superman kickass and face off against each other(see Marvel) in a more serious tone(while still being kind of ridiculous when you think about it).
