From the trailers that I've seen, this series looks like a fantastic production. I'm always wary, though, that any series based on a real institution which requires co-operation from that institution, is not going to be as realistic as it should be, warts and all, because that same institution would not give permission for any bad publicity.
I love the theme tune. Apparently its taken from this much longer version of a 1936 song from the big band and swing era called "Sing, sing, sing (with a swing)"
