Space Sci-fi TV:
I think the re-imagined Battlestar Galactica was great.
Non sci-fi:
I think Babylon Berlin is good.
I only watched the first series of The Expanse.
It's very subjective - if you enjoyed it then I'm glad. I'm certainly not in the majority among my friends in disliking The Expanse, but also not alone.
See, we have that in common. I may have to check out Babylon Berlin. Per your mention, I checked out the wikipedia entry for it. I do like a good period drama, as well as detective shows. Inspector Morse comes to mind. Anyway, I appreciate the exchange.
Did you watch Lewis? I enjoyed that.
Babylon Berlin is also one of those things that are particularly relevant at the moment as there are lots of parallels between the collapse of the Weimar Republic and the current state of the west.
I look forward to Babylon Berlin, for exactly the reasons you mention.
Beyond that how about non-sci-fi TV series? I'd like to know what you think are shining examples of television. Maybe 3 to 5 examples of non-sci-fi.
I know this sounds aggressive, but really, without knowing what kind of TV shows you think are "good", your opinion that The Expanse being bad, is without context. Maybe we like the same shows in general, but this one show is the exception. Who knows.
Also, maybe you watched the first 4 episodes and dismissed it as junk. That would make some sense to me, as the first few episodes were a bit rough. Or maybe you watched the entire thing, season 1 and 2, and it just wasn't for you.
