Much more serious, and way more ass kicking than its predecessor, this series was great to watch, I enjoyed it all the way through, until the last season. The series was much more grounded than its predecessor, having much more focus on the serious ninja qualities, and also by giving each turtle more of a unique personality. The array and quality of the villains also helped, with this shredder and others being far more of an opponent rather than the bumbling idiot of the previous show. The only issue I take is with the final season, mainly due to the turtles wearing clothes, the cosmetic changes that were made to the turtles bugged me, as they all seemed wholly unnecessary, that and their zipping around in cyberspace, it was something that didn't need to be more than a single episode, but it became the arc of the season. Anyway, a great series.
