It really was amazing. Bit meh after Season 3, but it really is one of the most smartly written animated shows I have ever seen.
Love some of the guest stars.
Of course Mark Hamil bringing in a legendary performance as The Joker, David Warner as Ra's Al Ghul, Roddy McDowell as The Mad Hatter, and a really nice performance from Adam West as The Grey Ghost (made even better because of the relationship of his character to Batman in the Episode).
