Well, I'm not going to list all of the obvious sci-fi here-let's just say I'm a fan. (B5, all ST, SG1, Farscape, Firefly, etc)
Now, the less obvious-
Life On Mars-LOVED THIS. People who have seen the Brit version bash the American but I couldn't get enough. Sorry it ended.
Torchwood-my favorite bisexual, unbelievable, crazy-insane Brit tv series
Primeval-they better do something more 'cause leaving Abby in a tree sucked
MASH-some of the episodes still bring tears to my face after all of these years-higher praise I cannot give
Friends-never got into the hullabaloo when it was the "hot" thing but I watch reruns whenever I can
Barney Miller- first, coolest instrumental theme song ever, IMO. Plus, Dietrich. And Yamato, the prototype for Coach on
Cheers
Cheers - more laughs in 30 minutes than Dane Cook and any two other comics combined- even Eddie Izzard or Robin Williams
nu
BSG- How good can sci-fi on TV be? Apparently, pretty damn good.
The Dick Van Dyke Show- this is comedy, plain and simple. That I can still laugh 40+ years later is a testament to it's universal tickling of the funny bone.
LOST-Jesus, almost quit watching, only to get sucked(BACK) in sooooo hard I don't think it will ever let me go. A huge ensemble cast-yet I know everyone's name. Think about that for a moment. How do you create a cast of a dozen or more and make each one memorable enough that viewers know all of their names? Like this....
Soap- crazy cool spoof of soap operas that didn't push the bar-it snapped the thing in half, tossed it in the dust and took off running
Mutual of Omaha's Wild Kingdom- I learned so much...
The Wonderful World Of Disney- 'Cause that's what Sunday nights were all about...
All In the Family- If you watched it, you know. If you didn't-I can't explain. You had to be there.
Monty Python's Flying Circus - Know what I mean, know what I mean?
Law & Order - just fascinating, and the characters felt real. Very real.
Sopranos- sympathetic mobsters? Yeah, right, it will never work...
I'm sure there's something I'm forgetting but this will do for now....
