I'm going to cheat and do two lists. One for current TV shows, and one for non current "new" shows. In no particular order...
Current shows..
Ice Road Truckers- (love trucks, love the drama and the unique hauls)
TF: Prime- (Best TF TV show ever. Nothing has came close)
Family Guy- (Again, no current animated show is on par. Not the Simpsons, not American Dad, Bobs Burger, nothin'

)
Harry's Law- Great law show!
Cops- Can't get better reality than this.
Shows that are either off air or not new..
24- One of, if not the best show on TV ever
Doug- One of my favorite shows as a kid in the 90's. Still watch when it airs on Nick's "90's on Nick"
G.I. Joe- My mom used to have to call me 3 times to get up for school at 7:15, but I had no issues getting up at 6:30 to watch G.I. Joe on saturday mornings.
Star Trek: The next Generation- Probably the one TV series that you can honestly say, is better than the originally series it was based on.
Monster garage-Back when Jesse James was respected. Loved seeing the beast's come out of that place.
