I'd recommend Community and Fargo the most for you. If you liked the Fargo movie you'll love the show even more

And Mad Men is hard to explain really. I guess to boil it down to one sentence it's about a man in an ad agency trying to find happiness in his life. But really it's about so many things. It's mostly interested in just painting a picture of the era and making really fleshed out characters. It's not a show that has a lot of shocking twists and turns or anything, so some may not find it the most exciting. But if you like character-driven stories with lots of good emotional moments it's very good. And it can be really funny most of the time too
