First, the game is not as good as City BUT only because of the bugs. So, the annoying things first:
Combat is not as fluid or responsive as it was in City
Camera can be annoying as you fight with it while in combat to move how you want
Bugs Bugs Bugs, freezes are frustrating...nuff said. At least they have not happened often with me, only twice so far.
The level up tree should NOT have been messed with, they should have kept it the same as City, being forced to follow the tree and not chose what you want is stupid and annoying
Where's the Batman Beyond Skin?!? Come on!
All in all, the MOST frustrating thing is that the combat is not as responsive as it was in City...sometimes you press "Y" but he does not block and your combat flow is screwed up. After playing Origins for a while I went back to City to see if there was a noticeable difference here, and there was, pretty noticeable actually.
Story is awesome and the new additions to detective mode in the game is fun
Combat is still the best aspect of this game/series despite the lack of response time that can occur in this game
The boss battles so far have been awesome, the game is slightly harder than City which is VERY welcomed and adds more depth to playing it I think.
All the side missions and crime watch etc. are all great
Basically, the game is the same as City with new game play/villains/things to do and explore...the only 2 reasons it is not as good as City are the technical reasons that could EASILY be fixed with a patch, if they would just do it: glitches and combat not being as responsive/quick as it was in City. I love the game, it is every bit as fun and addictive as its predecessor, I still have trouble quitting the game when I know I should stop playing, it's just too much fun to stop. Gamespot's review is worthless.
