I must say it is a mixed bag for me, especially in terms of SF.
On one hand, there are excelent shows airing right now that really nail what it means to engage in science fiction outside of the "pew-pew-lasers-in-space". Expanse is a great example - while I do not dig the series and know it mostly either from my girlfriend's summaries or wiki, what I've seen seemed like a great balance between solid research and fun, more outlandish ideas.
On the other hand, there are shows like Discovery. While I did enjoy the first season, with it's absurd mix of ideas from all over the place (Klingon Tombship straight out of W40k, Dune navigators, fungus warp and the Dark Galaxy of Space Fascists), the writing, especially when dealing with "science", was as horrible as I would expect from Alex Kurtzman, the man who pats himself on the back with technobable and then procedes with three script pages of stuff exploding loudly. It is the ultimate jocks science-fiction show - whenever anything bordering on science shows up, the absurd dialogue containing random words like "black holes" and "tachyons" literary ends with someone exclaiming "That's the power of math!" or "Yeah, science!".
Among my friends I often joke that the problem lies with a) changing demographics and b) making everything Star Wars. Apparently what we crave is just the aesthetics of SF, without any sociological or technological aspects that would hamper the pace of everything being blasted in the cosmic darkness. Imagine a non-satirical Starship Troopers TV series that actually, as in the original book, happens mostly during lectures and classes. Or a TV adaptation of "Accelerando" by Stross, or "Blindsight" by Watts.
SF rant aside, there still is the fantasy part. While fantasy has always been a minor part of my intrests, with honourable exceptions like Conan, Wheel of Time or the Witcher series (which I am obligated to know by heart as I live in the same city as the series author), I do find the situation more promising. Compared to the 90's, when fantasy shows and movies were good only in a campy sense (at best), we do have some high-budget, high quality series out there, and one thing that is great for sure is that there is no longer any stigma on the genre, now as marketable and profitable as it could ever be.
