Very enjoyable series. The computer animation gave Batman's outfit a wonderful textured look. I thought the depth written into the butler character was a wonderful addition. Making Alfred an ex-military man makes sense to me given his traditional gravitas in every Batman reprise I've ever seen. Bruce Wayne's martial arts abilities, intellectual curiosities, and maturity seem more believable if he was raised primarily by an erudite, canny, world-hardened ex-military officer. The mystery of Alfred adds to the allure of Batman's mystery.
I am saddened that there was only one season. I thoroughly enjoyed it.
