Here is what I perceive to be the best shows from each year in the 2000’s.

2000 – Curb Your Enthusiasm
The Seinfeld writer and co-creator’s sitcom about being a Seinfeld writer and co-creator. It is basically about his day to day life and the dialogue is all improvised. He basically gets into regular, day to day situations and then does the exact opposite of what you would expect a normal person to do. For example, refusing to give Halloween candy to teenagers.
Runners up – Survivor began the reality craze, CSI began the CSI craze.

2001 – 24
An amazing concept, having an entire season run as 24 real time hour long episodes. For a show about counter terrorism, they also never villainize one particular country and they always show citizens of that country or creed that do not agree with the terrorism.
Still need to watch – 6 Feet Under

2002 -Firefly
A great space-western by Joss Wheadon. Short lived (only the one season) and highly praised as being an oddball genre combination.
Runner up – Idol, but there is no way I could choose this show as a winner.

2003 – Arrested Development
It is a Comedy centered around the Bluths, a formerly wealthy family. It is presented as a pseudo-documentary format, including old family photos and videos, security camera footage, website screen shots and the most ridiculous cast ever. It is also shot with hand held cameras and uses no laugh track. Amazing Show.
Runner Up – Battlestar Galactica – A really close second for me, if it was an original story I would have chosen it as first.

2004 – Lost
Of Course. Probably the best show of the decade, even cynics of the way the show is running currently would agree that the first season is amazing. If you haven’t seen it.. well I’m not going to spoil anything.
Still need to watch – Deadwood – even Danny Devito twitters about how good this western is.

2005 – It’s Always Sunny in Philadelphia
The gang from It’s Always Sunny in Philadelphia are probably the most likable scumbags on television. They are really horrible people, to each other and others, but I just cannot stop watching.
Runners up – Iron Chef America, The Office US

2006 – Dexter
Set in Miami, this show is about an everyday normal blood spatter analyst that has been trained to be a serial killer of serial killers by his deceased father. This show’s first season was so amazing that no one thought that they could keep it up, but they really have.
Runners up – Heroes, Top Chef

2007 – Flight of the Conchords
The show follows a two-man band from New Zealand, as they seek fame and success in New York City. They break out into many hilarious musical sequences every episode.
Guilty Pleasures – Greek, Gossip Girl, Kid Nation.
Still need to watch – Madmen

2008 – Fringe
Co-Created by Lost co-creator JJ Abrams, Fringe follows an FBI Fringe Division team based in Boston, Massachusetts. The series has been referred to as the new X-Files.
Runner up – True Blood – Now an enjoyable show, the first season was rubbish.

2009 – Flash Forward
Based of the novel by Canadian author Robert J. Sawyer, the basis of the show is that everyone on the planet simultaneously loses consciousness for 137 seconds, during which people see what appears to be visions of their lives approximately six months in the future. They then try to figure out what the visions mean as well as try to ensure that they either happen or do not happen.
Runner Up – Bored to Death
Guilty Pleasure – Glee, Admittedly far from a great show, this teenage musical dramady is still full of heart warming moments and well played villains.
There are still a few months left of this decade and there are still a few shows to premiere. The only one I can see possible taking the 2009 title from Flash Forward is V, we’ll have to wait and see.
