If something can be much more directly and simply parsed as a misfire in the writers' room, it's probably worth stopping to consider that.
As I often remind people: every Star Trek episode speaks to someone out there. Many times, the episode you merely tolerate can be someone else's first-ever episode, or absolute favourite episode.
For the first year I was a part of fandom, I was really the only person I know who liked TMP. I started watching TOS and TAS, but still preferred TMP. Over the years I found more fans who were on my wavelength, and the movie did tend to get reevaluated and appreciated anew over the decades.
Fans do seem very keen to blame the writers' room these days. Some people are quick to shout "Lazy writing!", but anyone who's ever done some serious writing knows that there's not much laziness involved, unless you never get to the end, of course.

I think it's more like the "Dallas ending"...
Poor Pam Ewing not only dreamt a whole season of "Dallas", she also dreamed a season of "Knot's Landing" as well.
And there was some more weirdness. Didn't Miss Ellie get remarried in that dream season, but was still married after Pam woke up? IIRC, "Knot's Landing" never addressed Bobby's return. They just never mentioned him again.
