When thinking of the 2000s and TV shows, some of the most iconic series of the last 20 years come to mind. Among these are shows likeThe Wire,Mad Men, andThe Sopranos,series that have not only withstood the test of time, but went on to re-define television in the 21st century.
But the turn of the century also marks the launch of exciting shows that didn’t get as much attention. A few of them have returned in some fashion, one is even still on the air. But each has something in common: they had a dedicated legion of fans and received positive reviews yet have never been considered among the best shows of that decade.

10’Cougar Town' (2009-2015)
Created by Bill Lawrence & Kevin Biegel
Courteney Coxstars in this sitcom as a divorced woman trying to start over in her 40s. Newly single with a teenage son and wine-loving friends, Jules (Cox) is living a life much different from the one she did in her 30s, and that can be terrifying. Each episode tackles her challenges and triumphs as she embarks on new later-in-life adventures.
Cougar Townaired for its first three seasons on ABC, and following its cancellation, TBS picked the show up for three more, splitting the show’s run between the two networks. One of the reasonsCougar Townis so underrated is that the first season was poorly reviewed. But theshow ditched its main premiseand hit its stride in subsequent seasons, with several of the seasons even earning a100% Certified Fresh Rotten Tomatoes critics' score.

Created by Greg Garcia
An interesting take on the concept of karma, Earl Hickey (Jason Lee) is a small-time thief who realizes that every time something good happens to him, something bad follows. This realization comes to a head when he buys a $100,000 winning lottery ticket, then loses it. Earl decides to change the course of his life by making a list of all the bad things he has ever done, then making up for them all, one by one.
My Name is Earlwas not only underrated, the show was also abruptly canceled. It ended on a cliffhanger, so fans never got the closure they deserved.My Name is Earlwas funny, had a great cast, and offered a unique story with a positive spin. The show gives viewers something to think about, behind the humor, too, through thought-provoking analysis of how every action and decision in life has repercussions.

8’Medium' (2005-2011)
Created by Glenn Gordon Caron
Patricia Arquettemight be a huge movie star, but she has also had some notable small screen roles. One of her most known is as Allison DuBois in thesupernatural dramaMedium,a series that follows a medium who works with the district attorney to help them solve cases. What’s most interesting is that the premise is based on a real medium of the same name who claims to have worked with law enforcement, though the agencies she says she worked with deny her involvement.
Whatever the truth behind the real-life story that inspiredMedium, the fictional series is enthralling and fascinating.

Whatever the truth behind the real-life story that inspiredMedium, the fictional series is enthralling and fascinating. Arquette is convincing as a woman who is able to talk to dead people, and proves her claims are real by shocking others when her dreams lead police to making arrests and finding bodies. Arquette won an Emmy Award for the role in 2005. Those who watched it, loved it. But whileMediumcontinued for seven seasons, it largely flew under the radar.
