I didn't say it. John Campbell said it in the August 1967 issue of Analog.
True but you did use him to back you up a bit. However, correction noted.
As for how I feel about it, Twilight Zone was about one third what one could loosely call "science fiction", though generally of an extremely primitive variety (doesn't mean it wasn't often a brilliant show, but "asteroids" with Earth gravity and atmosphere were commonplace). I only caught about a third of the eps of The Outer Limits, since Natalie was covering it by that point. A lot of it was goofy. Some of it was quite good. It was more definitely science fiction, but more 50s B-movie type stuff in genre.
Twilight Zone was fantasy, which is why I never include it in a list of SF shows. It had some science fiction episodes, but everything happened because it all happened in "another dimension."
The Outer Limits could be goofy, but it also presented a lot of hard science fiction. Almost to the point where you felt like you were watching a high school science film. For the era, I felt it was a cut above. Episodes like "The Architects of Fear" "Nightmare" "The Man Who Was Never Born" "Soldier" "Demon with a Glass Hand" and "The Inheritors" are among the the top tier with me.
The Invaders is schlock -- The Fugitive with nothing compelling about the lead, and alien invaders who are silly. The same letters that pan Irwin Allen usually lambast Invaders, too.
I'm far from the series' most ardent fan, and Roy Thinnes was dull as Sunday school. He was a chess piece, moved about week by week as he came across as a crackpot most of the time. With his tailored suits and crabby disposition, the series' dead end concept was doomed to a short run.
That said...
The first season was wonderfully paranoid and often very spooky. Even scary in the right mindset. This was an odd choice for QM, but he wanted a new version of
The Fugitive and this was the show. But nope.
The Fugitive is a show I consider remarkable consistent in quality for the first three seasons. It wasn't always exciting, but it was generally interesting and often compelling. It was a high bar for QM.
12 O'Clock High was, as one critic put it, wartime psychotherapy. Every week was another officer's or soldier's personal problem. But Robert Lansing was a hell of a lead and the series had some amazingly good episodes.
Is it perfect? No. Sometimes, it's not even
good. And sometimes the science is kaka. But that was par for the course in contemporary SF, too. As Sturgeon said, 90% of everything is crap.
I do consider
Star Trek the best science fiction series of its day. Whether it's the best of all time is an endless debate, but it is my favorite.
