Yardbarker (via MSN) has made a list of 25 coolest TV characters of all time and as usual this list is a mess. Here are few that most can agree that maybe are good choices:
Sydney Bristow (Alias)
What was so cool about them?: “The red hair was a nice touch, but make no mistake: No job or challenge was too big for Sydney (Jennifer Garner). If there is a more potent, intelligent and prepared female television character to handle any international crisis that comes her way better than Sydney, then we'd like to meet her.”
James "Sonny" Crockett & Ricardo "Rico" Tubbs (Miami Vice)
What was so cool about them?: “No shave, no socks, no problem. These dapper vice detectives (Don Johnson & Philip Michael Thomas) were trying to rid the city of Miami of drug lords and other scum. They also possessed two of best undercover aliases in TV history as Burnett and Cooper.”
Omar Little (The Wire)
What was so cool about them?: “Who says villains can't be cool? Probably those who never watch Omar Little (Michael K. Williams) do his thing. Omar was an organized stick-up king and criminal. He was smart, cunning and actually had a conscious.”
Olivia Pope (Scandal)
What was so cool about them?: “One has to admire those who usually tend to get what they want. That's Olivia, one of the most powerful women in television history. Yet, Pope (Kerry Washington) did it with flair and didn't mind taking down or stepping over whomever she needed to do it.”
Buffy Summers (Buffy the Vampire Slayer)
What was so cool about them?: “How many people can balance school, friends and killing vampires to keep the Earth spinning? Buffy (Sarah Michelle Gellar) seemed to pull it off without a hitch. OK, maybe it was all too much to ask for a young woman to do at times, but Buffy was a battler. She was also a great friend and was literally willing to put her life on the line for those she cared about - or didn't even know, for that matter.”
