It’s not a “Marxist” show but Star Trek Deep Space Nine. You’ll get a good mix of lighthearted/fun and serious storylines on a scifi setting, the background of which is about a formerly colonized people reconstructing their nation (well, planet) under a provisional government, while outside/imperialist powers try to get a hold on a geopolitically significant region that falls under their newly reclaimed territory. Many episodes are about totally different things, just various scifi “what ifs” or interpersonal stories of the main characters, but many are about diplomacy, war, terrorism, freedom fighting, what to do about war criminals and collaborators, whether to build a moderate/compromise government or continue fighting, how superpowers as allies affects a former colonized nation’s sovereignty, those kind of topics.

I think most communists would agree that libraries are a good resource.

As a side note, there can also be libraries of things other than books and media, like toy libraries (so parents aren’t pressured to buy tons of toys but kids can still borrow and play with different toys), tool libraries (so people in a community don’t have to all individually buy tools that they might only use occasionally), home appliance libraries, electronics, musical instruments, etc.

These services are more marginal under capitalism because they’re not for profit. Under capitalism, big libraries of items which can easily be borrowed for free is not a welcome idea for capitalists seeking to profit of off false scarcity of their products, and its harder to maintain non profit services like this. In a communist society, there wouldn’t really be a reason to hinder the expansion and enhancement of libraries to make them even better resources for the public.
