According to the source, the combat doesn’t work at the moment due partly to the game’s free-roaming camera system, partly due to the mashy hand-to-hand combat, partly due to the limited range of moves Batman can use making the whole thing very repetitive. Since there is really no official release date or even an announcement yet, there is still plenty of time to work on the game.
On the bright side though, Pandemic’s game is based off the movie but the game’s events are actually set after the events of the movie.
