I have to say that I don't ever remember a period of time when TV was as great as it is now. There are so many good new shows on that you can't possibly watch them all. But I thought I'd point out my two new favs.
Dexter (Showtime) - This is a Showtime original series about a cop who is a forensics expert by day, and a serial killer by night. The twist is that he only kills bad guys. If you don't get Showtime, you can view the episodes on Showtime's website at http://www.sho.com/site/dexter/home.do (and they've edited any nudity or f-bombs so it's actually a better place to view it). Dexter is obviously pretty dark but nonetheless a very cool show.
Heroes (NBC) - This is a cool new show about a group of people around the world who have superpowers. They don't know each other, but they're slowly starting to find out they are connected somehow. This show has conspiracies, cool bad guys, a slowly unfolding mystery, and more. You can also watch this one online at http://www.nbc.com/.
By the way, this new trend of networks posting their episodes online to be viewed the day after they air, is by far the greatest thing networks have done in a long time. If you missed a show, or you'd like to check out a show that only comes on during church or work or whatever - don't fear. Just watch it online! Sweet!
So now you can watch these shows along with LOST, The Sopranos, Dog the Bounty Hunter, 3 CSI Shows, 3 Law & Order Shows, SportsCenter, Boston Legal, ER, Medium, House, American Chopper, oh, and Dr. Phil, Oprah, SuperNanny, Trading Spaces, and whatever other crap your wife makes you watch.
