So would the average punter's reasonable takeaway from the Trek cognoscenti be that, proportionately, the more consequential conceptual missteps of Enterprise (and perhaps Voyager too for that matter) can be laid at the feet of the UPN decisionmakers?
Possibly. I think maybe for keeping Berman on, rather than anything else.
The reason I say that is this: I was watching the Berman/Braga talk on the S1 Blu-ray of Enterprise. In this, they discuss falling ratings and discuss that they had been consistently falling since Deep Space Nine - a decade previous. Having seen some TNG and DS9, the only difference I can
really see between them is setting and cast. They all seem to approach things in much the same way, all the jokes are always told the same way
("Ah, is that what you hu-mans call hu-mor?"), etc. To keep someone on, in charge of a show that has been consistently failing year-on-year for nearly a decade, and let them make it in exactly the same way???
It was bound to happen, the cancellation. TV had changed (it always does), and Enterprise needed to be more different than just the same thing "before kirk lol".
It did knock some shape into itself in S3, and to be fair, I enjoy it all, but I can see it has problems.
