I have watched and loved so many shows over the years. I am a bit of a TV addict. My favourites are below (in no particular order):
Scifi/Fantasy:
Stargate (The complete Series) - (SG-1, Atlantis, Stargate Universe) - This is a big undertaking, but well worth the time - Google the best viewing order.)
Battlestar Galactica
Farscape
Humans
Game of Thrones
Westworld
The Expanse
Dark Matter
Fringe (Get through the slow first season and it hits its stride mid-season two and then it is pure brilliance thereafter)
Firefly (It was a travesty it was cancelled - but well worth watching the 14 episodes and follow up with the movie Serenity that wraps things up - wonderful show)
Orphan Black (Tatiana Maslany is simply brilliant playing multiple clones)
Comedy Drama:
Lucifer
Chuck (This one is a lot of fun - one of my all time favourites)
Being Erica
Drama:
Bloodline
The Wire
Dexter
Breaking Bad
Friday Night Lights (This is far more than a show about American Football)
House of Cards (US)
Billions
Bull
Jericho
The Man in the High Castle
Teen Drama. (Try not to judge - these are excellent shows)
Gossip Girl
The O.C
One Tree Hill
The Vampire Diaries
Roswell (Obviously this is also Scifi)
Happy Viewing
