Star Wars: Andor is one I can highly recommend, and that’s coming from someone who found everything outside of the original trilogy to be extremely meh. Andor punches so hard above its weight and source material it’s absolutely crazy. It’s some of the finest sci-fi I’ve ever seen, and in themes is genuinely antifascist. Give it a shot even if you have star wars fatigue, it’s that good! I can’t wait for season two.

Another show that I’d recommend (though slightly less enthusiastically) would be Peaky Blinders, which is about British WWI vets who become gangsters after returning home. The acting is incredible, and it covers a surprising amount on working class struggles of that time, the persecution of socialists by the state, the rise of fascism in Britain with historical people, and is overall pro-socialist. The only reason I recommend it slightly less than Andor is it can feel a little repetitive if you binge it, so I recommend spacing out episodes a bit if you can to hopefully avoid that feeling. It is a great show despite that.

I’d also recommend Firefly if you haven’t seen it.

You may enjoy Turn, which is an older show about the spy network during the american revolutionary war, which has some great acting, and at least a good revolutionary spirit of resisting tyranny.

Lastly, and this one might be a tough sell, but I personally enjoyed Blake’s 7, which is an old low budget scifi from the BBC revolving around a small band of misfits as they essentially try to find ways to undermine a totalitarian empire with an advanced ship they find. It can be super cheesy and campy at times, but some of the actors kinda carry it (Paul Darrow), and it has a certain charm.
