Apparently season 3 will be far more allegorical in it's political elements.
Thank. God.
One of the biggest things I have loathed with modern writers is the hackneyed, often shoehorned CURRENT YEAR political plotline. It dates the show, ages like soured milk and is often completely at odds with the setting portrayed.
"Oh, but Trek's always been political."
It has, you're perfectly correct.
However there is an absolute gulf between using political themes to tell a story and beating your audience over the head with a jarring cause celebre that becomes old by the next news cycle.
I skipped out on ENT during first-run. I watched it during the Quarantine and this was my takeaway: S1 was kind-of okay (the more they focused on stuff specific to the 22nd Century, the better), S2 was a snore almost until the end, S3 was not my type of thing (I think it's basically Star Trek for Republicans), and S4 is the only season I truly liked and would recommend. If ENT ran seven seasons, and continued like it was in S4, I'd have liked it overall. But, because it didn't, I don't like the overall show, just that one season.
ENT suffered the mood and simple whims of the viewing public at the time. We were in a period in which the public were in a very vengeful mood after 9/11 that lasted a number of years and the hippie-peace, love and exploration message that was fairly core to Star Trek was really falling flat with general audiences especially.
From what I remember the Studio meddled with the tanking ratings and basically told Trek to go to war, hence the Xindi arc being the entirety of Season 3 and is very much an attempt to capture the mood at the time. Especially as the architect of the very real life version was still at large and people wanted him strung up.
But, like my own pointing out above, you get to re-watch it 20 years after its original broadcast... and it's aged to the point you dismissed it as "Trek for Republicans". It wasn't. It was trying to recapture the public mood as best it could from that holdover of 2001/2002 and the shock and anger felt from it.... in 2003.
Now while it was being written in 2002 and shot in 2002 it was very much the cause celebre, the invasion of Afghanistan had gone so well we were hoping to find Bin Laden within weeks, the Taliban were getting their arses absolutely kicked and obliterated pretty much any time they so much as popped their heads out etc.
By 2003 these feelings had somewhat subsided. Leading to ENT to once again miss the boat and the cultural zeitgeist.
So to dismiss it as "Trek for Republicans" is a bit disengenous but you also need more context of when it was shot than someone who just wants to watch the space explorers do their space explorerer thing 20 years later.
