I am a big fan of the original Gatchaman, to the point where I cosplayed as Ken recently. I kinda like the new series, but the old one is still better. I am hoping that the old characters make an appearance.
Tatsunoko is probably my favourite anime studio. Other series I like from them include Yatterman, Tekkaman, Time Bokan, and The Flying House, as well as their adaptations of Pinocchio and Cinderella.
