It had Michael "Christophuh" Imperioli in an entertaining role as a nasty detective, and Harvey "Full Frontal" Keitel as their Captain; Gretchen Mol as "No Nuts," the only policewoman in the sexist, gritty '70s. Imperioli was always good for sneaking some B-side quote of a single; on the last ep he mentions about "drinking up all the salty margaritas in Manhattan," a nice nod to Warren Zevon's "Desperadoes Under the Eaves."
He also had a nice quote- "We're livin' on a rock hurtling through this big cosmic jambalaya, and all we can hope to do is find a couple of people who make livin' on this swingin' sphere remotely tolerable." Heavily paraphrased of course. I liked it.
The ending was as crazy as expected from a show with this concept, and I liked it. Nice wrap up- certainly different from the BBC series, which was a lot different.
