HMMM my most favorite is Alias,rumor has it this is the last year, and I enjoy Lost as well. Whoever had Monk on their list forgot The Deadzone which is a bit more sci-fi. From a ladies perspective I enjoy SG1, SG Atlantis, and BattleStar but with my work schedule and such haven't been able to keep up even trying to record it I got behind. Atlantis is an easy one to start with and for me Battlestar is a bit hard to follow at times but one of the older ladies at my job just loves it. CSI anything especially the first one is great as well. Also you could always go back to some of the oldies but depending on your age and tech ability you may not enjoy them as well.
