I watch Dexter and love it...hopefully will watch this weeks tonight. Brewers and Packers are taking up way too much of our TV time right now. Especially the Brewers.
I couldn't get into Treme either. One on my list to watch is Shameless...my dad really liked that one...just one season so far. I enjoyed Episodes and think that they are making a second season. Six Feet Under is fantastic (best ending to a series I think that I have ever seen). I like True Blood but DH won't watch that one. He loves Game of Thrones and I like it but not like he does.
We watch a lot of sci-fy and LOVED Battlestar Galactica. Also Stargate, than Stargate Atlantis and Stargate Universe (best was Stargate the first series). Now we are watching Babylon 5. Of course all the Star Treks!
We both really like Glee. I also like but DH doesn't watch things like Vampire Diaries, 90210, Melrose Place....that stuff I watch after he goes to bed. Another series we both liked a lot (and yup DH did) was Gilmore Girls.
I'm not watching new series for the most part. We got so burned last year with basically our favorites being cancelled....and than the idiots in charge won't even write in an ending and just leave you hanging. At this point, I'm willing to try things on HBO or Showtime....or wait until they are hits and watch on DVD or even when the whole thing is over.
