It's more downbeat compared to stuff before the BSG reboot. The best of the downbeat is probably the Expanse. But I really miss my Eureka like shows. Sci-fi was on a roll other than the wrestling stuff in the late 2000s and early 2010s.I'd say it's still good, I've enjoyed pretty much all the current sci-fi shows I've been watching lately.
We even had shows like Psyche and White Collar that were generally more upbeat than the average show today. Shows were generally more positive in nature.
I'm mostly binging stuff doing that era. Finished up original 4400 and White Collar during lockdown as well.
I find most of the new Trek shows pretty downbeat as well.
