I'm able to judge these things pretty quick. I always have. In 1992, all I'd seen was TNG and the TOS Movies. Then I watched TOS itself. And it took me two episodes to realize I liked TOS better than TNG. "Where No Man Has Gone Before" and "The Corbomite Manuever" sealed the deal.
It took me three episodes until I realized I liked DSC as much as TOS. "Context Is for Kings". That one took longer than usual.
I don't need seasons upon seasons to judge things. I've been watching TV for 40 years. I can look at what's there, go with my instincts, and project. I assume certain things will improve or iron out. I take that into account.
Lower Decks, by its design, will never match TNG and DS9 in my opinion. But VOY and ENT were a slog. Lower Decks doesn't feel like a slog. That's why I put LD where I do. And I think time will bear that judgment out. If I turn out to be wrong, I'll say so.
I never get this thought. The idea that "you can't judge something on the basis of only a small amount released." The Shortest short trek or the smallest episode is the *easiest* thing to judge in the world, compared to some 178-hour long series. It's nearly impossible to judge all of Star Trek: The Next Generation, but nearly impossible not to judge an episode you can watch over a bowl of soup.
It's obviously comparing apples to oranges (I prefer apples), but we already compare TNG's 178 episodes to TOS's 79 episodes to Enterprise's 98 episodes. Adding in LD's 1 episode (or "1/2 episode") to the mix doesn't change much.
I think the issue isn't with whether you can judge how much you like you like one episode of a show compared to how much you like another entire series, or even if you can estimate how much you think you might like one show (based on one episode) compared to how much you like another entire series, but whether you can rank the quality of one show based on one episode compared to the quality of another entire series.
Saying you "place" a series in relative position with other series is vague and can be taken as either "comparative quality" or "comparative liking". I think Kpnuts took it as "comparative quality" which is very hard to defend with only one episode. If you meant it as "comparative liking", I think it is more justifiable since you do know what you like and you don't like, but it is still shaky because it is based on only one data point. I didn't like DS9 as much at TNG when it started, but I now think DS9 is the better show. I liked ENT a ton, but fell off kind of quick, and was brought back by season 4's jump in quality. I really liked DSC's and PIC's starts, but there were some rough bits in them that didn't show up in their first 3 episodes in each show. So far, I am loving LDS, and I hope it stays that way.
