"Some"? 29 episodes across TNG, DS9, VOY and ENT. That's even one more TV episode than Jonathan Frakes directed. (although Frakes also directed two movies)
Come to think of it: Star Trek had a bunch of actors directing episodes every now and then. I don't think that many other TV shows did that, didn't they?
The shuttle bringing Freeman, Rutherford and Shax to the surface has a profile and colors resembling a Tatooine landspeeder, and the staff handling planetary landings were uniforms resembling Imperial ones and speak in pseudo-British accents.
Also, the background music when that shuttle landed sounded like it came straight from a Star Wars movie.
Voyager is alright. It's just very uneven. What drags it down is that the producers only very rarely took big swings that had a lasting impact on the characters or the show. Voyager excels at being episodic television. There are a bunch of stinkers (as there are on any TV show) but when it's good, it's really good. It has some of the best Trek episodes.
Maybe use an episode guide with ratings (for example Jammer's Reviews, Ex Astris Scientia or IMDb) and skip the episodes with low ratings.
However what I don't think is justified is the label as one of the worst Star Trek episodes. Is it nuts? Yes. Is it annoying that they have the technology to bring everyone back to Earth and simply de-lizard them after the trip, and then it's never brought up again? Also yes.
But it's nowhere near the worst episodes because it's neither offending and un-Star Trek (like TNG's Code of Honor) nor is it boring. It's actually pretty entertaining for the first 35 or so minutes. It just goes off the rails at the end.
Here is an excerpt from The Fifty Year Mission (book 2) by Mark A. Altman and Edward Gross. I highly recommend those books. They are super insightful about the behind-the-scenes stuff from the first 50 years of Star Trek.
I mean, DS9 wasn't as popular as TNG back then – both in terms of ratings and fan reception. Many considered it the black sheep of the Trek family. Berman focused on Voyager. So it was chrystal clear to every fan with even half a brain that DS9 would never get a movie. Perhaps Voyager had a tiny chance but by the time it concluded its run viewership had been in steady decline, and then Nemesis tanked.
Reverse-DRS. Every driver who is more than 1 second behind another driver gets DRS to catch up but then they have to work hard for the overtake.
It's probably nonsense but I'd love to try it out in a handful of races.
