Had to think long and hard, because I've always thought the show was perfect, start to finish, and didn't need anything else (not even Saul, but that turned out great). So my first instinct was to be hesitant about this, but seeing it's Jesse's story made me happy. His character was such a fucking delight and one of the most fascinating arcs I've ever seen on TV.
So I guess I'm down for this. I'd have to binge the original series to prepare. Have you ever seen something so good, you almost don't want to revisit it for fear of running how perfect it seems in your head? That's me with this show!
