I avoided watching this for 20 (!) years, because the reviews were ambivalent. But it's really fun. It's not awesome, like the Kirk/Spock series, but it's also (thus far) not excessively moralizing like TNG.
This is the only Star Trek (for me) that captures the wonder of the original series. The writing isn't great, but that was never a thing with Star Trek. They're also a bit kinetic, say, with discovering new Warp-Civilizations.
I also really appreciate that the crew is basically white, except for one black guy that's not blackity-black.
Even the chicks are fine. The writing for the Asian chick is a bit insipid, but it accurately reflects the chick version of the 'hero's journey'.
Unfortunately, they've introduced Time Travel, so I guess a few of the episodes are going to be tedious.
I quite enjoyed it. For me, season three is the best out of the series. The cast do a fine job, but honestly the episodes with Jeffrey Combs shows what a great actor he was for the franchise.
Season 4 fell off a bit and culminated with the utter disaster of the series finale. The final episode is absolutely worth skipping.
