They don't hit the mark directly, but they're still on target.
A funny choice of words, as I found that to actually be one of the biggest problems with the game...not that the new studio "didn't hit its mark", but in the sense that more often than not, Batman doesn't hit his mark.
By this I'm referring to the Combat in the game in which the target prioritizing is completely screwed. The biggest example of this that I encountered was during one fight in which there was a baddy with a gun standing next to a baddy who had picked up a fire extinguisher to throw it at me. I initiate the Disarm-Destroy move, pointing in the direction of the two guys. Now, in the previous games, it would recognize the guy with the gun as posing the bigger threat and as such would have Batman jump towards that guy, take away the gun, and take it apart. Not this game. In this game Batman just jumps towards the nearest weapon - regardless of how threatening it is - and Disarm-Destroys it. This led to Batman jumping at the guy with the fire extinguisher, taking it away from him, and throwing it across the room to destroy it...and then get pumped full of lead by the guy with the game.
But that isn't the only example. The Batclaw always targets the person furthest away in the direction that you're pointing. As such instead of grabbing the guy that's running up to punch you in the face, you target the guy dancing around behind him and get punched in the face as you try to pull that guy towards you. The jump-evasion technique also has lousy targeting, often leading to you just dive-rolling in the general direction you're pointing rather than jumping over an enemy in that direction which, again, leads to more getting punched in the face.
Quite honestly, I kept saying "as long as they don't screw up the combat, I'm sure I'll enjoy it." Well...due to the wonky prioritizing/targeting, they actually DID manage to screw it up...so that bumped the game down quite a few pegs in my book.
And to say that the exploration wasn't much fun is only part of it. After about 2/3rds of the game has gone by, most of the rooftops have snipers on them, which more or less negates the fast-travel system (unless you like being shot at by snipers) and makes going from one place to another rather tedious as you're pretty much forced to clear out every roof that has a sniper on it. But yeah, the fact that you're just arbitrarily prevented from going on top of certain buildings (such as the power plant, as mentioned in the review) becomes a pain since you have to go all the way around it every time, and it's a pretty damn big building.
As for bugs, the only one I encountered was a particular elevator that Batman seemed to enjoy falling through the floor of, ending up in an eternal freefall/glide underneath the area.
