I actually like the Batmobile stuff. It was everything else that was the problem. 3 levels in the entire game and the first one isn't until half way through and makes you go back cause they ran out of time to make a proper game. Combat is very stagnant and all the variations are thrown at you early on which makes things more tedious than the Batmobile. Predator challenges are borderline terrible in this game. It's literally faster to just brute force your way through by fighting. No boss fights as mentioned (Good ones anyways). They didn't get Dini to write so you have a very good plot utterly destroyed by poor writing. Great game, but its a very sloppy thrown together game. There's little infiltration and absolutely no difficulty progression. Sad to see the series decline the way it did all because of the mainstream "open world" business. A shame cause if they had the time they could have made something amazing.
