Carnivale

I have never heard of HBO's Carnivale until recently. It is the first thing since Stephen King's Dark Tower series to capture my attention so fully. I just started watching it and cant stop thinking about it during the day. It is very detailed and rich in the way the plot unfolds, making it worth watching several times over to see what you missed.

You can catch up on all your old episodes using HBO on demand. Or if you are not already a Netflix Member then go ahead and rent seasons one and two so you can watch them even without digital cable. I'm a Netflix subscriber myself, and am generally very happy with it.
