From a recent post on Slashdot:

…”Batman can’t really afford to lose. Losing means death — or at least not being able to be Batman anymore.”

I had never thought of it before, but, yes, the implicit pleasure in any such masked hero movie is that he cannot lose. Losing means either death or being unmasked which is tantamount to death.

In real life, most people get second chances. Not so for the masked hero. It’s an accepted premise that heightens the tension in every battle. Nice trick.
