My top 5 favorites:
Six Feet Under
Nip/Tuck
Deadwood
Rome (wating for 2nd season!!)
Sopranos

This thread is going to get messy!

I can't believe no-one has mentioned the-greatest-TV-show-ever-in-the-history-of-the-unoverse yet:

Buffy the Vampire Slayer Most of the time great fun, some of the time, unsurpassed genius.

Then amongst others already mentioned, I like:

24
Sopranos
Firefly
House
Shark
My Name is Earl
The X-Files (a past firm favourite that went sour after about season 5. Previous seasons were as good as TV can get sometimes.)

The UK has a handful of recent gems:

Life on Mars (this should actually be first on your list, before it gets remade )
Peep Show
Spaced (if you like Shaun of the Dead/Hot Fuzz you'll get this)
The Office
Extras

Currently America is hogging the airwaves, but go back a decade and there's a lot more UK stuff that could hold its own today like Prime Suspect or Cracker.

To watch:
24
NCIS
House
CSI

To own:
The Sopranos
LOST
The Simpsons
Allo Allo
The X-Files (untill season 6, except for season 9 which was pretty good again)

Ohh there are so many good ones.

Battlestar Galactica ( the new ones )
Dr Who ( the New ones ( plus I love the old ones but they are an acquired taste! ))
House MD
Desperate Housewives
Lost
24
Blake's 7
Twin Peaks
Inspector Morse
Wire in the Blood
Taggert
Cracker

I'll stop there - lots more are bubbling up!

In no particular order.

Doctor Who
Lost
Hogans Heroes
Honeymooners
Southpark

I just bought a friends collection of 500+ DVDs - mostly box sets and TV series. I'm not quite sure where I want to start.

500.... That's even more than my entire collection...!

Question No. 1 Can I bring the popcorn...? 

Quote:
I'm off from work for a few months so I have a lot of time for movies!

Question No. 2 Where can I get me a job like that?

With the 500 DVDs I'll hit the 3,000+ mark - once I add them all to my collection! Although I already own quite a few of them, the price was unbelievable and couldn't pass it up. 
Answer 1: As long as it's popped on the stove and has real butter! NO microwave stuff <shiver>
Answer 2: Have a piece of machinery fall and get your left arm crushed.    I'll be fine but I miss working!

My question - where's YOUR list?!

I was/am a big fan of the original, but I love the new one - in fact I like it more than the original.    Still feel weird/wrong saying that.

I think they have done a fantastic job of re imagining, making it sufficiently different so that it does not damage the memory of the original.

I would have hated a scene for scene remake with modern technology, but they have gone down a nice original route imo.
