I don't have Showtime BUT for whatever reason Time Warner is giving me 3 free months of showtime for Christmas, including "on Demand." I'm happy to say that I've watched first two seasons (I'm on the Season 2 Finale) and am enjoying it.
I must say that, with the exception of Saul, I don't really find most of the characters likeable (including Carrie) BUT not necessary to enjoy the show.
Btw, I can watch thru season 3. How many seasons have there been?
