If Trek is about the themes and the setting, than you're likely the sort of person who thinks The Orville is a Trek show, since it's Trek without the canon.
This has basically been my sense of
The Orville.
Now, I want to be clear here: I don't
like The Orville. I don't think the jokes are funny, many of the characters are very irritating, and the format is outdated. People say, "Oh, it's TNG," but really it's much closer to the worse parts of ENT, where they tried to "humanize" the characters by (for example) making Trip answer a third-grader's "poop question," and kept iterating on the same old plots that had already been exhausted by the
Voyager ended. (Hello there, "ORV: Into The Fold"! You were much better when you were "ENT: Dawn", and even better when you were "VOY: Innocence"!)
But
The Orville has aimed at the essence of
Star Trek in a way that
Discovery has not. It's doing so pretty badly with it so far, but you can see a lot of room for improvement, for it to find its own voice, for it to incorporate some of the conventions of modern television, and become a
Trek for the 21st century. I'm going to keep watching in hopes that it does so... and because those little glimpses of what
Star Trek Is ("About A Girl", "Mad Idolatry") have been so tantalizing. I missed
Star Trek so much that I'm willing to give pretty bad
Star Trek a chance. I mean, hey, I gave TNG and ENT chances after their awful first seasons, too, right?
The problem with
Discovery isn't that it has changed the formula.
Trek's formula
needs to change in the 21st century. But
Discovery has abandoned
the essence of the show in a way no other show has done or
could do while still being recognizable as
Star Trek. I don't see a path forward for
Discovery where it remains recognizably
Discovery but also starts doing the sort of exploration and character realism that define
Star Trek.
ANOTHER THOUGHT EXPERIMENT:
Imagine you've watched
Discovery but with all the proper nouns removed, as well as the arrowhead badges, the title cards, and some of the incidental equipment design (like the iconic dual-nacelled ships). Basically, you watch
Discovery but with the continuity references bleeped out. Everything else remains, so you get the full stories and character arcs. Once you're done watching, someone asks you what franchise you think
Discovery is a spinoff of. How do you answer?
My answer is that it's a distant-past prequel to
Battlestar Galactica. I can see people saying
The Expanse, based more on its set design. But
Star Trek? I might get there eventually, but it wouldn't be my first guess.
To my mind, that's a real problem for a show that wants to be thought of as
Star Trek.
new mathematical law:
the longer a conversation on star trek continues, the risk of the discussion being hijacked by mentions of non-trek show Orville continues exponentially inverse to the rate of the word "continuity". All trek threads will eventually be hijacked by the virus that is Orville.
You're begging the question, aren't you? If
The Orville is Star Trek in some sense, then it
deserves to hijack all the threads!
