This game is great, it unfortunately is not better than Arkham City (I still believe that is a top 5 game of all time) and may not be better than Asylum. The 3 main gripes I have are:
1.The boss battles, it's been said already but they are disappointing.
2.The Arkham Knight twist, very disappointing and it turns out to be very unoriginal IMO
3.No challenge maps, are you kidding me? Half the fun was playing the maps as Batman and his allies and there is nothing yet.
I'll stick up for the Batmobile, it can be a bit tedious but people have been asking for the Batmobile forever now. I still give the game a 8.5/10 and it's probably a top 30 game of all time for me. Arkham City just set the bar too high and this game didn't meet the expectations. Graphics are insane though, beautiful game and Scarecrow was awesome. I am kind of disappointed with the lack of Bane, Mr. Freeze, Killer Croc, Ra's al Ghul, etc. Some of the side mission villains like Deacon Blackfire and Professor Pyg were lame. Also, I hate Firefly.
