But Star Trek is not an audiobook or radio-drama. If we handwave production design as irrelevant to continuity, we're basically giving disproportionate responsibility and credit to the writers in what is supposed to be a visual medium depicting an extrapolated, science-fiction(-like) reality set in our actual galaxy, with a good measure of technical consulting.
When a new artist takes over a comic book, it's pretty much expected these days that they'll use their own distinctive art style, redesigning the characters to fit it. This is seen as a good thing. An artist's distinctive style is what gives that artist their creative identity and their fanbase. People
want to see artists draw things their own way instead of copying what their predecessors did.
So you have it backward. Respecting artists' freedom to reinterpret how they portray a fictional universe is not marginalizing them, it's freeing them to be creative. Because that's the real point here. Continuity is not the sole purpose of fiction. It's just a tool in the kit. The purpose of fiction is to be
creative. To exercise your talent as a storyteller or artist. It's not about cold conformity to some index of facts and figures. It's not about creating consistent Wikipedia entries. It's about imagination and talent and artistry and emotion.
Star Wars is very clear on that subject: design continuity matters.
I am so sick of people assuming that just because
Star Wars does something, that somehow requires
Star Trek or other franchises to follow suit. There is no universal law for creativity. The whole thing that
makes it creative is that
everybody gets to do it their own distinct way. (Not to mention that
Star Trek is a decade older than
Star Wars. We were here first, so we don't have to copy the latecomers.)
Star Wars and
Star Trek are very different entities, and each does things in ways that suit its distinct nature. SW reuses the same designs because it's always, always been an exercise in nostalgia. It was created as George Lucas's tribute to the adventure serials and movies he grew up watching as a kid, so it's always been intrinsically backward-looking and celebratory of the past. But
Star Trek looks in the opposite direction, toward the future. It was always meant, from the start, to be cutting-edge and forward-looking, to push new ground in TV production and extrapolate design and technology forward into the future. So it's in character for ST to keep advancing its visual futurism to fit evolving real-world technologies and aesthetics.
