This new animated series has been criticised, mainly in the States, for not being as deep as the older 1990's animated series. Though it probably won't be as remembered with quite as much affection as the older series, it is different enough and good enough to enjoyable in its own right.
The focus of the show is different, with the stories having a more superhero feel than the 50's crime show of the 90's show or the Blade Runner feel of Batman Beyond. They've made The Batman character a young man, three years into his career. All the characteristics that make Batman great are here but shown in a more obvious way. You'll see his determination in Traction, his angst and guilt in the Big Chill.
In this show Batman uses more technology and hardware to catch his prey. Is this a cynical ploy by the producers to make kids buy toys or a sound creative decision, showing how the Batman can defeat his redesigned and more powerful rogue's gallery of foes? I think it's the latter. Bane on venom now grows to ten times his original size, whereas Mr. Freeze is a genetic mutation needing only a wave of his hand to cause a storm of ice. With Mr. Freeze they have also reverted back to his 1960's TV origin story of a man who was frozen by Batman and wants revenge. (Mr. Freeze is voiced by Clancy Brown the first animated series' Two-Face and you'll also hear 60's Batman Adam West in the cast.)
The last two episodes are a great finale even to the point of borrowing ideas from Alan Moore's The Killing Joke. The Batman is something new, fresh, zestful, colourful and enjoyable. And while I enjoyed some episodes more than others I'd still recommend its purchase.
