I don't watch much tv on a regular weekly or day to day basis so I enjoy getting the DVD sets from netflix where I can just sit down and watch an entire series season in a few evenings on weekends. Since I don't watch much regular TV I don't bother to pay for subscription channels like HBO and Showtime and stuff. That being said though, I have enjoyed a number of the HBO series dvds including:
The Sopranos
Oz
Six Feet Under
And from regular TV: Lost
I hear people say that Lost is the best show on network TV right now. I didn't hear about it until a few episodes into the second season though so I got the season 1 DVD's from Netflix and I gotta say, it is a pretty damn good show. Now I can't wait until the second season finishes so they can release those DVD's. I wanna know what's in that !$%@# hatch!!
