I’ve watched all the episodes at one time or another. I watched some of them when they were originally aired, especially the older stuff.
Some of them I watched on Netflix, some of them on the WB broadcast station, some on the UPN broadcast station and some on the CW broadcast station. The CW is what’s left of the WB and UPN, but don’t ask me for dates. I believe the oldest ones were on the NBC broadcast station.
I wouldn’t be doing my duty if I left these out. “Star Trek: Discovery” starts airing sometime in 2017:
Both the “original” and the “enhanced” versions of the first series are available on DVD and Blu Ray. I’ve seen both.
You can’t start this batch without first watching the Stargate movie from 1994:
“Stargate Infinity” was an animated spin-off that no one watched, not even me. “Stargate Universe” did so poorly that it killed the franchise. From what I understand, however, a new series started being developed in 2014.
These were all one series each, except for “Battlestar Galactica”, which had a prequel series called “Caprica”. I haven’t watched it yet and I really don’t have any wish to do so.
Ignoring the original “Battlestar Galactica” and “Galactica 1980”, it started as a miniseries in 2003 and was picked up by the network as a regular series the following year.
I will revise this article later this year. I intend to include some TV series I’ve neglected today. I simply don’t have the will to remember them all and I don’t want to screw things up.
