Almost 4 years later, let's review my answer.
I just noticed the title of this thread and thought that I probably have already answered. I was pretty surprised to see what I had answered. My opinion has changed quite a lot in just four years.
Here are the five series I've watched over at least twice.
Babylon 5
- This has a special place in my life, but I'm not going to rewatch it. The series is outdated in almost all manners. Really bad CGI, slow tempo at times, simplistic story lines and 20 episodes a season (so many fillers!). I do hope they'll do a reboot, but I'm not holding my breath.
- To me this was updated version of Babylon 5. It too is showing some marks of being outdated. 20 episodes a season makes it hard to rewatch. And the show declined after a great start.
- The last season wasn't it's strongest, but I still belive the series is very intense and gripping. Probably going to rewatch it sometime.
Monty Python's Flying Circus
- Monty Python remains to be the best comedy ever made.
- I tried watching Heroes Reborn but man was it horrible. They couldn't hire all the actors, so they tried to fake it. It failed miserably. Heroes had a great 1st season, but it seems it was a stroke of luck. They couldn't repeat their success, because they didn't understand themselves.
Honorable Mentions, these series had a good season and numerous bad seasons. I did enjoy watching them back then, but I'm not missing them anymore.
Walking Dead
- I'm Surprised to find this here. To be honest, I think it's better than Heroes. Not watching this anymore, but I'm quite sure I enjoyed this more than Heroes. I still can't stop thinking how'd I survive during Zombie Apocalypse. I keep coming up with strategies how to surive and manage a community of people.
Yeah, it had a great buzz, but that's about it. Not missing it at all. There are better series for this list.
I spend a lot of time watching this one, but had to drop during the final season. I realized the show isn't going anywhere. They repeat the same pattern, and I'm not going to fall for it.
Good series, interesting plot and setting. Not sure if I'd watch it again. I dislike the time period for various reasons, but this show made it interesting for a while.

Special Honorable Mention
Game of Thrones - I'm not sure if I'm a fan or not. I enjoy reading the books and watching the show, but on the other hand it feels soulless. There's just too much stuff and too little time. Some characters only get about 20min of screen time per season, and they are still considered 'main cast'. But I'm all for having a high quality fantasy TV-series in mainstream.
Okay, I'm not sure what was I thinking here. Let me be clear. Game of Thrones is the greatest TV series ever. I've watched the entire series about 3 times already. We keep discussing about it with my wife. We have our own fan theories. We named a puppy litter after (Jon, Dany and Arya) it.
Revisited List:
Game of Thrones - This series makes everything else look bad.
Vikings - The atmosphere on this series is stellar. Not always a fan of the plot, but this looks and feels so great. Can't stop listening to norse folk music.
Sense8 - In a sense, this is updated version of Babylon 5. Even though they don't look anything like each other, they share the spirit. The core message in both series is "We are one". It shows that despite our differences, all of us are connected to create a whole that is indivisible.
Black Sails - I hate pirates and ships. It took some time before I started watching this, but I was immediatelly hooked. Well produced and written. I wish it had one more season, or perhaps a Treasure Island spinoff
Westworld - It's great to see a series of this scope to take a serious swing at AI. The topic a has deep underlying philosophical discussion, and I think Westworld is on point on this one.
Honorable Mentions:
Expanse - I really enjoyed the first season. It felt like it was the upgraded version of Battlestar Galactica. It's best scifi on TV. Also read some of the books based on the series. For a while this was on upper list, but had to move down for Black Sails. The 2nd season wasn't as strong, and I'm feeling they are underbudgeted.
The Borgias - It's partially the original Game of Thrones. Sad to see this scheming family to be cancelled prematurely.
Handmaid's Tale - Not exactly a fan of the setting, as it seems slightly unbeliable, but otherwise it's doing a great job. Eagerly waiting for the next season.
Stranger Things - I'm a D&D player and a 80's kid. Such a nostalgia trip.
