No. 2: Fight Choreography/Cinematography
It is not a secret that no live action Batsuit in the last 30 years has been a picnic for the actors that dawn them, and the crew members that dress them for that matter. It is notoriously difficult to put on, to take off, and to perform some of the most basic functions in. In every previous film before BvS, and after Batman 1966, if it looked like Batman was moving and fighting in a 60 pound, unventilated rubber body cast...it's because he basically was.
Directors have had to get creative to get around this. Partially by being very cautious with the potential situations Batman can find himself in while setting up scenes, thereby making his physical limitations less apparent. If they indeed are going to create a scene impossible to perform in the Batsuit, they must rely on quick jerk movements and rapid cuts to create the illusion of fluid movement. This is present in TDK when Batman is dispensing small groups of enemies. In TDKR when against a single enemy that is meant to be equally skilled as Batman, in this case Bane, it looks like two drunken football dads trying to finish it in one epic punch because they've only got about 4 or 5 good punches in them. With Tom Hardy forced to slow down his fighting so as not to outshine a Batman obviously burdened by his own suit. They even in TDK (cleverly) bring attention to the fact that Batman cannot turn his head and wants Lucius, his personal tech engineer, to solve the issue for him.
The DCEU has found a way around this with a seemingly more flexible, more versatile suit. Combine this with carefully placed special effects give us our first truly impressive, truly effective, truly authentic live action Batman. The already classic warehouse scene and the final battle with Doomsday are the best representations of this. We finally have Batman seamlessly flowing from gliding, to grappling, to swinging, and fighting in a way we've never had on film before. Many saw this and were immediately reminded of the "Arkham Series" video games which are revered in part for their fight mechanics. Now we also have confirmation of Joe Manganiello cast as Deathstroke. Appearing as a prominent villain in the Arkham games and well established in comics as Batman's physical and mental equal, we are pretty much guaranteed even better Batman action yet to come.
