There are two TV shows that it seems no one knows about, and yet, I think, are the very best on TV today. Better than West Wing. Better than CSI:xyz. Without further editorializing:
MI-5 - A british show about spies. Brilliant.
24 - A US show that covers a single 24 hour period over the whole season. Each of 24 episodes covers 1 hour in 1 hour. Outstanding.
