Netflix currently boasts 695 episodes of Star Trek from multiple series, so there's certainly a lot to watch. Netflix also revealed that close to 12,000 fans have watched every single one of those 695 episodes.
The top 10 most watched/rewatched episodes come from Star Trek: Voyager and Star Trek: The Next Generation. Drilling down further, you'll find six episodes of Voyager and four episodes of TNG with Voyager's series finale "Endgame: Parts 1 & 2" topping the list.
Now, we're not saying Voyager isn't good, but it does seem strange that episodes of Star Trek: The Original Series and Star Trek: Deep Space Nine didn't break the top 10. So, the next question is how they formed the list.
According to Netflix, here's the methodology:
Netflix analyzed the viewing data of 104 million members across 190 countries who have watched the following Star Trek series on Netflix: Star Trek: The Next Generation, Star Trek: Enterprise, Star Trek: Deep Space Nine, Star Trek: The Original Series, Star Trek: Voyager. In an attempt to look for data beyond default behavior, the first two episodes from any season ones were omitted from the data. “Rewatch” is defined when a member returns to watch at least 6 minutes of an episode they had previously completed.
Six minutes, huh? Could that be it? Is there a Voyager fan out there who loves a certain part of "Endgame"? Or are there Voyager fans out there who realllly love the show. Maybe they really like the two-parters? To be honest, I've got nothing here. But maybe one of those 12,000 fans out there might want to offer some insight?
