Just watched the final episode... decent conclusion, hated the execution. The last couple of episodes the dialogues have been quite bad, when in the beginning they were awesome.

I'll wait for the manga to release a couple of more volumes and start reading that... from what I've seen around the anime split from the the story and went its own way.

The fights were pretty good though, and the Initial D-like car chase was great.

Overall, great unique series... glad I watched it.
