Well, I watched the first ep of 5Ds.
Pros:
* Yusei looks extremely cool, I like him a lot better design-wise than Yugi and Judai
* Shiny opening end endings. The opening and ending songs aren't half bad themselves.
* Conveiniently placed endless alleyways for long bike duels
Cons:
* Correct me if I'm wrong, but in the copy of the ep I have, the subs call the game D-Wheeler. But it sounds like D-Rider.
* First ep was basicly just showing how cool this new Riding Duel thing was, and DIDN'T EXPLAIN THESE NEW RULES, which was reeeeally confusing.
* I refuse to accept the existance of cops who do their buisness with children's card games. JUST NO.
* Also, the first ep managed to be 23 minutes long and not interesting at all
But it does look promising.
