For the past couple of years, I have been putting up a series of posts presenting arguments for which shows count among the greatest sci fi and fantasy entries of all time. I will be continuing with that series, but now is the time for you to do your part. This poll lets you cast your vote for which shows you believe count as the best. You can vote for up to ten, so that should give you several to choose from when making your selections.

The list, as it stands, has entries for all of the shows I have written posts for so far, plus more that I am working on now. This is not a complete list at this point, just a fairly comprehensive one. And you can nominate shows to add to the list if you find something missing. If a show gets nominated five times (each by a different person) in the comments below, on one of our social media accounts (Blue Sky | Facebook | Mastodon | Twitter), or on our discussion page, it will get added to the list, and each of those nominations will count as a vote.
These are the criteria for the shows included:
-
It must have notable science fiction or fantasy elements. Horror is acceptable as well, but only if it also includes sci fi or fantasy elements (i.e., I am not looking to include slasher horror on the list).
-
It must have aired on one of the linear channels or on one of the streaming services (web series like The Guild or Red vs. Blue are not being considered here).
-
It must have ended its run two years ago or earlier (which currently disqualifies Stranger Things). That gives time to let the show settle and allows people to decide if it truly was a classic, even if it might have had a disappointing finale. It also keeps this from turning into a Save-My-Show poll for series that have recently been cancelled. I do make exceptions for shows like Doctor Who, Futurama, and Black Mirror that have already had extended runs and established themselves as genre greats. But for the most part, I will stick to this rule.
The links below are to the posts making arguments for and against whether each show counts as an all-time sci fi TV great. For the shows without links, I will add those as I create posts for them. Feel free to debate the rankings or any of the shows included in the comments below, and also at the discussion link over on r/SciFiTV. The list is sorted by series title and then by year.
