I wholeheartedly agree with everything you said, EXCEPT that they’re not that different. I think most of the shows have a very unique tone, especially when you go from TNG to DS9, but unless I’m mistaken DS9 was intended to be “different”.
Maybe a few of the new ones are pretty similar, that’s for sure. But the older ones? Nah.
But I’m not looking for an echo of what I just said, so by all means if anyone wants to disagree with me, by all means! I don’t get a chance to talk about trek outside of the internet and I’d love to hear other takes on them.
Edit: and only after posting did I realize you meant the FANS aren’t that different, but you do go on to say the shows are pretty consistent so I’ll leave this here.
