Seriously, I don't know why I keep hearing people complain about this. If you were happy with the first film, then you were approving of the whole 'Bruce Wayne in a mask' origin as opposed to 'Batman the Ego'.
Batman is open to many interpretations. However, going back to Bob Kane and Bill Finger, continuing through Adam West, Denny O'Neill and Steve Englehart and up to Frank Miller and others, it was always "Bruce Wayne in a mask." Bruce Wayne just happens to be obsessed with avenging his parents' murder by warring upon criminals while wearing a mask.
