It was quite possibly the best Batman.
I didn't see it in the theaters, because I was afraid of copycat shootings. But I got it for Christmas, and I watched it with my niece...we both loved it.
I have a hard time picking between the 1980's-1990's Batman serials, and the Nolan serial. I think both have great movies in them. The new one is much, much darker, but the Batman/Batman Returns/etc collection was a lot of fun growing up.
I hope they don't kill the franchise, though. If Nolan decides to make another one, that's fine, but we don't really need Batman massacred in remakes.
