The Nolan Batman movies bundle was $15 on iTunes so I snagged it last week, and so I've also rewatched Batman Begins. I loved this in theaters, didn't like it so much the 2nd and 3rd time, but it was love ALL OVER AGAIN this 4th viewing.
Someone else posited that Ra's Al Ghul is the Liam Neeson we should have seen as Qui Gon Jinn; a mysterious, calm, devoted, emotionless master who is never entirely clear about his motives. Lovely. His deception works well, his use of manipulation to create a being, rather than teach him... and in the end the pupil going wayward: these are all things which would have been great in the Star Wars Prequels if GL could have been convinced to let someone else hold the reins.
Unlike many here, I like the sequels well enough, but I agree that Bats is taken off in a different direction, not one that I enjoy as much as the entirely broken, compulsive, relentless comic book character. And the voice does get ridiculously stupid by the third movie. Maybe that's why the made Bane's voice even more silly, so no-one would notice?
Anyway, I agree, BB is the bee's knees.
