Got a chance to watch last weekend, and it does not disappoint!
The animation is sublime throughout, but where Redline maintains the next level cool is with the vision and scope of the story. Sure, it's ultimately a simple race tale, and for those amped up by it's high octane race visuals from previews and scenes online, it doesn't disappoint. However, there's more to this anime then just mindless racing action (not that it might not have been better served with more of that), but it offers a full story, on a few levels, with many sub-plots, character arcs... more than you'd expect from a title like this. Also, with it's intergalactic race circuit, it's of course rich with supporting characters of amazing variety. Basically, there's a lot to love, and that makes Redline utterly re-watchable. It did not supplant Dead Leaves at the top of my anime list though. Here's hoping we don't have to wait several years for another anime to challenge for the title!
