5Ds was awesome if you can see past the absurdity of card games on motorcycles. There's really a lot more to it.
Zexal season one was absolute shit, and was just original series again with different characters, like the Pokemon BW anime. But unlike BW, it picked up 70 episodes in and got intense as hell. Aliens and ghosts fucking shit up. After Vector showed up, it isn't even about card games anymore.
