I was reading reviews about Christian Bale's Dark Knight and the voice that Vincent also found annoying, and this was my favorite review:
Reviewing the film for MSNBC, Alonso Duralde wrote that Bale's Batman in "Batman Begins" "sounded absurdly deep, like a 10-year-old putting on an `adult' voice to make prank phone calls. This time, Bale affects an eerie rasp, somewhat akin to Brenda Vaccaro doing a Miles Davis impression."
Bless Alonso for mentioning Brenda Vaccaro. Genius.
