Bat-Sh*t Crazy!
I'm still in awe of the fact that it took game developers this long to finally come up with the perfect way to represent the Dark Knight in video game form, but damn it, if it wasn't the worth the wait! This is like the kind of stuff that Paul Dini would probably see if he took a whole bunch of anti-depressants and soaked in a hot tub for a few hours. And those mind-jacking Scarecrow scenes are just priceless.
