Really liked Bale's portrayal in BB, then was very disappointed with the sequels having him retiring after a year.
Largely because of the "realism" factor that someone that dresses up as a bat can't do this crusade for very long.
On the physical side, Batman's body taking a beating & leading to his not being on the job long was an interesting take--one almost every other superhero film never addresses, especially if the character is not enhanced. With Affleck's Batman, he was the seasoned version, but even he addresses his shortcomings by having to up his training to face Superman, so he was not retiring, but his acknowledging his very human body's potential weaknesses was a nice, realistic manner. In other words, he just cannot jump out of bed and think he's ready to face a potential threat of that magnitude.
