Great watch, would watch again, and do recommend.
I feel like I have a thing for the isolationism of deep sea bases. "Bioshock", "Deep Blue Sea", "The Meg", "Underwater", "The Abyss": just the idea of being far away from any help in the most dangerous living conditions possible on the planet.
Add in a mysteriously time traveling alien sphere and let bake in the survival situation where people are losing their minds and things keep manifesting into existence.
It's a little insane, but it has a quality cast, plot, and some great action for all the characters being a bunch of nerds.
