Discovery hasn't yet made an episode I don't like. At worst I've thought "they could've done X better", "Y wasn't a big enough problem to affect my enjoyment", or "I'm going to wait to see how Z plays out." With a continuing storyline, not starting from scratch every week, there's always something there I'm interested in. Because I've been interested in all of DSC's long-term stories.
In older Trek series, where oftentimes the story would start from scratch, I'm at the mercy of potentially coming across an episode where I don't like any of it, tanking some episodes altogether for me.
As a result, with all of the old series, even the ones I preferred, they all had at least a few episodes where I'd give a 5/10 or less, by the time they got to 40 episodes. I haven't given any episodes of Discovery a 5 or below. And there's only one episode I gave below a 7. Two if you count Short Treks. They were "The Escape Artist" (6) and "Unification III" (6.5).
Same goes for Picard, where I haven't yet given anything below a 7 at all. If Picard can keep up the same quality level it had in its first season across its run, I might actually like it more than Discovery in the long run. But it's too early to tell at this point.
How's that for controversial?
