Like many here, I think close 'Game of thrones' and'Sherlock'. Personally I want to add a Comedy series 'Parks and recreation'.
Quantum leap. Few remember. (1989 – 1993)
The main character traveling in time, took the appearance of other people, helped someone. He had to fix the problems that man who was possessed. After all it turned out to fix it, went to another person, hoping that the next leap will bring him back home to his body.
Classic.
Detective Agency of Dirk gently (2016) - lethal mix of mystery, fantasy and Comedy!!!!!!!!!!!!
Wreck
I remember, I remember! That was a great series.
Sherlock, game of thrones, Vikings, followers, true detective. In General, a lot of good TV series filmed in the last ten years.
1. Clinic in my opinion is the best series. Then the laughter and tears.
2. The walking dead - the first seasons I watched with pleasure, and then solid snot went, but worth a look.
3. Scum - carbon series, though only the first 2 seasons. Then brad went and shut it down.
4. The Big Bang theory - specific humor in the series))

Please pay special attention to the works of Stephen Miata! He is a true genius, he makes the truly interesting stories, professional, knows people better than they themselves.
Now I watch the show shadowhunters, great fantasy, very much, more such serials were removed. I advise to look not regret it, off just not possible from view.
The Punisher simply elegant series, the last episode knocked me out completely - I'm even a little taken aback after watching almost believe that these characters belong to the marvel universe.
Can't speak for how my favorite TV shows are pulling for the best.
Among them may be noted: Get smart; Quantum leap; Alf; Command And; Firefly; Taxi (TV series, 1978, not to be confused with other works Taxi); Sledge Hammer.
And many more of them, according to the modern not so good.
The animated series is another category in which there is something to mention.
