What do you think of the jaw / mouth hole in Batman costume
One of the most persplexing scene was when a bomb goes off in front of Batman's face and his jaw comes out pristine.
Why does Batman need this jaw hole anyway?
The scene would be more realistic if Batman wears fully closed cowl / helmet (Iron-Man style.) I think Nolan chose to make the hole as small as possible because of the possibility of disrepancy in scenes like this. But still, there is a hole which would make an explosion hurt his mouth area, lips and teeth.
What do you think if Batman doesn't have a hole for his mouth? Is it too iconic to remove? Or it would make it more realistic?
