Possible the best tv program ever

Epic, amazing, awesome, riveting I run out of adjectives for this series.

A slow burning story set over a very short period of time. Some episodes follow on day to day but it's not always clear what the passage of time is. The story might be slow but it is gripping. The actors are all amazing without exception. And Ian McShane is something else as Swearengen. The most shocking thing about this program is not the language (which makes Danny Boyle's Train-spotting tame) but that is was cancelled unfinished after 3 series.
