What is the most underrated TV show?

Personally, I'd say the TV show "Psychoville" is totally underrated!

It's a British "dark comedy" that really is a unique combination of horror, comedy, drama, and the surreal.

It's written by and stars by 2/3 of comedy the trio The League of Gentlemen, and it's probably one of the most bizarre shows I've ever watched. It lasted for two seasons (with a Halloween special thrown in), and features some of the most creative and twisted characters ever written for TV: Such as a mother-and-son serial killer duo, and a dwarf that has supernatural powers.
