I gotta say...
Whoever came up with that eye alien was a fricken sci fi/horror genius. That thing makes my skin crawl. I'm blown away how damn creepy it is. An alien monster for the cinema ages there.
To be honest episodes 6 and 7 were good, but not imo on the level of the first five episodes. The season finale however was freaking excellent.
I also thought that Atom is the synth Boy Kavalier built when he was six. And YES the cliff hangers left a lot of potential directions.
