Dreadfully slow and unresponsive combat. Thugs are way faster than batman in this game and I was spending most of my time just countering during combat because if you strike at an enemy who is about to attack you, they will land their hit first almost every single time. A post in an old forum thread I found sums this up better than I ever could:

"Fighting used to be a beautiful, rhythmic activity. Now it's about finishing a move and bracing for another surprise pop-up counter prompt to appear. If you try to actively engage enemies in your own terms, a counter prompt will appear off the beat and the game will simply assign you damage and break Freeflow. Countering moves while performing other moves, known as cancelling, to deal with incoming thugs is just not the same, something was changed: be it the thugs' close-in segments of their attack animations have been sped up, Batman's move's recovery segments have been shortened or maybe even the counter move effect segment is misplaced in the frameset, causing you to miss the counter if you press it too early or too late during the performance of a different move. I'm not sure what it is, but whatever it is, fighting is just not what it used to be."

It isn't unplayable but it is boring.
