It's a show about aliens invading Earth. But it gets more complex as some of aliens want to work with humans rebelling against the other, a new alien species wants to destroy the one's already here adding to galactic politics and suspense drama.
Set in immediate aftermath of invasion, it has a post-apocalyptic vibe, a really complex and well thought out plot, good mix of action and drama and some very underrated but well done graphics. A very good cast tops the lot!
Really good sci-fi that I've never heard of till last week. I've been binge watching 3 seasons already!
