Buy it when it comes. Or watch on Crunchyroll. It's fucking amazing. If you liked Baccano you'll love this. I hope they don't do that retarded thing like "Season One... Part One" bullshit that I've been seeing lately.
And I hope if they have special features, it isn't about the fucking dub. Who cares about the dub? I liked it when they had the japanese director commentary subtitled on the DVD for Paprika, and I hope they do that for anime from now on.
Watch it. Watch it after you come home from work and kiss the wife, hubby, kids or dog. It's great shit!
