Some recommendations:
Mabel - Mysterious ghost story.
We're Alive - High quality Zombie TEOTWAWKI.
Our Fair City - Dystopian adventure with comic momments. Stay with it until Season 2, it takes a while to warm up but is one of the best.
EOS-10 - Scrubs in Space.
Wolf 359 - Space mystery adventure.
Liberty - There are two related series: I recommend starting with 'Critical Research' for the worldbuilding and then proceeding onto 'Tales from the Tower', which is extraordinary.
