Any alien series?

I'm looking for sci-fi dramas, Is there any series with aliens? It'll be my first time watching dramas, so I don't have any previous examples... But I love human-alien interactions (like on Mass Effect and The Orville, were you can clearly see their cultural and biological differences clashing some times).

I'm not here hoping for a Star Wars, Mass Effect, Halo, Star Trek kind of thing. But I'd love some good alien sci fi series, if there's one. (I heard of Parasyte the grey but not interested, since I'm not interested on Parasyte as a whole, manga, anime or drama.)
