One caveat: since most of these shows are created/shown on cable networks, they possess more bad language, sex, and violence than you'd find on the mainstream primetime networks.
1. House of Cards - get sucked into political machinations
2. Boardwalk Empire - what happens in Atlantic City stays in Atlantic City
3. Battlestar Galactica - embrace your inner nerdiness
4. Grey's Anatomy - it's okay to like a chick flick
Two sentence summary: Sexy doctors, weird medicine, raw relationships, Shonda Rhimes, flawed characters - what's not to love? While I don't even know any doctors on a personal level in real life, these characters are so richly drawn that I look forward to glimpsing their lives each week.
5. Vikings - and it's okay to watch the eye candy and close your eyes to the fighting
6. Orange is the New Black - don't be embarrassed that a women's prison fascinates you
7. The Walking Dead - sure, there's safety in numbers, but at what cost?
8. Sons of Anarchy - this one is rough trade all the way
9. Justified - good guy on the edge
10.Game of Thrones - makes fantasy cool
Two sentence summary - Another epic tale, this series has managed to intertwine the macabre within a story line of several people trying to gain the throne of a fictional world. Its flawed characters are entertaining and horrifying as they explore the primary themes of all epics - loyalty, greed, lust, revenge, patriotism, and faith.
Obviously, I tend toward the dramatic and toward television that isn't from one of the big 3 networks. I also tend toward more masculine style shows, but idk what that really says about me. Any psychologists/therapists want to analyze that one? On second that, maybe that's a bad idea.
You'll notice there really aren't any sitcoms on the list. That's because I'm generally not a fan of that canned laughter track they use; it annoys me. If you're a sitcom lover, then I can only vouch for Seinfeld, Friends, The Big Bang Theory, and The League. Otherwise, you're on your own.
I also don't care for reality shows; fiction is what makes my heart sing. If you want a reality show recommendation, all I can suggest is The Voice/American Idol. I do love a contest based singing show - my guilty pleasure. Maybe it's because I have such fond memories of watching Star Search when I was a kid.
There you have it, my recommendations for television. If you're game, go back and start watching with season 1 of any and all of these shows. I'd love to hear what you think of them. :)
