Re: Batman's fighting style - new Batman, what should his fighting style be like ?
Who cares? Only obsessive fanboys are playing a scene like that in slow motion or creating a gif for a 2 second moment. All that matters is that it looks good in the film up to speed with the rest of the scene/s.
All action movies have this kind of stuff.
"Guys, what would be your reaction if Alfred was Batgirl in this movie? You go watch the movie, everything cool, halfway through, Alfred becomes Batgirl."
