All the other Narita Ryohgo fans out there are on this already, but if you somehow missed Baccano! back in ought-seven then let this be your introduction to anime so awesome that exclamation points are compulsory!  Baccano! was proof that you could have a story about immortals over the course of three years that flows like hot grease, and Durarara! is what we all wanted Persona: Trinity Soul to be.  Brain’s Base does the animation again, and they have Baccano! and Spice and Wolf references in the first episode so we don’t forget.  The animation quality makes those of us watching anime in the 90s weep.  GG is all done with Trapeze and they’ve taken on Durarara!, so you know the fansubs are quality.  Download it off Animesuki now!
