"I had my doubts about Arkham Asylum because it looked like a dark, gritty game with scary horror elements, and how can you have scary horror when you're Batman, ostensibly the most capable fictional character since Jesus? (Ooh, edgy!) And how can you have dark grittiness when you're Batman, a man who swishes about in his underpants and a fabulous cape? This does feel like reaching for the low-hanging fruit - and Batman is nothing if not a low-hanging fruit - but I just love that bit in The Dark Knight when Gary Oldman and Aaron Eckhart are talking about bringing down the mob, and it could almost be a scene from The Departed, until Batman flounces in wearing pajamas and a bucket on his head and no one bats an eye."
