I like the font chosen for the Batman Begins. It's definitely simple and in that regard, I think it's in constrast to the Batman Forever & Batman & Robin font which looks a little overdone IMHO. I've always had a problem with the Batman movie fonts. The original film's looks kinda lame and too 80's but the Batman Returns font isn't bad, just typical Times New Roman looking thing.
The Batman Begins font just seems classy to me. Not elaborate at all, and it reminds me of the original Alien movie font. Just clean cut and to the point.
