Checked this out because I get AppleTV+ for now so why not. And they're usually so good at sci fi. Severance and For All Mankind are two of my favorite shows.
But I had an uh-oh feeling when they lead with a sequence that implies this is going to be handy-wavy fantasy horror and not actually sci fi at all.
Then we progress to the space-based part of the story, which has danger and action reminiscent of For All Mankind, without the attention to scientifically plausible detail. Just a lot of explosions and gore with people back at Mission Control wringing their hands.
Jonathan Banks is good, as always, but the rest of the cast doesn't really leave a distinctive impression. Not for me. Bye.
