It’s interesting that they take this view of canon, which I feel would be disputed by some. Some kind of official definition of what “canon” refers to would be good.
The official Star Trek canon. Surprisingly for many it says nothing about continuity. That's a fan thing.
But... many of the criticisms I’ve seen here and elsewhere relate to the storytelling of DSC. The quality of the stories and the depth of the characters.
Do follow some of the links and read the comments too, Discovery has been savaged for it's "sjw agenda".
That doesn’t make me happier that one of the show’s top priorities and announcements was about character sexuality, or that the only healthy relationships in the entire show have been homosexual.
Why would that make you unhappy? Did TOS really become famous and iconic for the quality of the stories and acting?
Clue; nope.
As far as Trek history goes, I found The Outcast compelling, way back, as a mild introduction to sexuality as something other than male/female. It was a bold move at the time.
A positive move, but hardly bold given the climate, other shows and movies were already going far further as a matter of course. In many ways we've actually made backwards steps in the meantime.
Gay characters are a totally appropriate addition, but heavy-handed social agendas don’t tend to make for good Star Trek, Star Wars, or any other tales.
Ok, what exactly does make for good Star Trek? TOS and TNG were in many ways defined by heavy handed social agendas, whilst DS9 was notable on any intellectual level for deconstructing and reframing those agendas. We didn't see Nichelle Nichols in the White House, Whoopie Goldberg seeking out a role in the show which inspired her or countless progressive groups adopt Trek as an icon because of the Shakespearean scriptwriting.
Watch "The Omega Glory" or "Let This be You Last Battlefield" and then tell me Discovery is heavy handed and badly written by comparison. It really isn't.
This is precisely why VOY is referred to as "TNG lite", because it had all the superficial elements of the show sans the willingness to make statements, direct or allegorical. ENT suffered much the same faults, both shows lacked any substance and the spaceships, rubber foreheads and phasers started to look pretty crass without it.
Trek's cultural impact has been about social commentary, not shooty adventures in space.
Discovery's handling of gay characters wan't very heavy handed. It wasn't all that different than the straight relationship in the show.
It was just a relationship, plain and simple. It would have barely warranted comment if they had been mixed sex, much less somehow been highlighted as symptomatic of the shows failings. It seems to me bizarre that someone would argue in all seriousness their position isn't based on prejudice whilst highlighting a portrayal of a relationship which amounted to about twenty minutes (arguably amongst the
best twenty minutes) of screen time across the whole season as somehow being the cause of the show's issues and openly stating that it was "heavy handed" simply because the characters were gay.
It was, as you say, pretty understated and mundane, which is exactly what was so positive about it, the characters and their relationship were shown in terms of normality, avoiding shock value at every turn. Yet still "I'm not being homophobic but......" keeps rearing it's ugly head.
What I fault the show for is making a conspicuous priority of it, at the expense of other priorities that matter more, like making a great show. That’s where the heavy handed part comes in.
I'll grant the show had it's flaws, but so did every iteration of Trek. Certainly it was far stronger than TNG season one which many would happily rate as the worst Trek ever made.
Can you, however, provide any causative link between those failings and the social agenda? Can you provide any clear argument or case backed by evidence that the show in any way suffered
as a result? Can you make any remotely coherent case that the show could have been improved by removing those elements and taking a more conservative position with regards to it's casting?
