Just watched the first few episodes on NF.
Pretty fun, quirky, show. I like Ellie Kemper, found her funny in the 21 Jump Street movie as the chemistry teacher. She does a great job here with her quirkiness, facial expressions and I like her odd reactions to various "modern" things and use of language.
I would have thought under the premise of the show she was isolated from society a lot longer but she went in when she was 14 or so. which fairly old enough to have something of a grasp of society and reality (and arguably have enough of an education to be a somewhat productive member of society.) From pre-release info I would have thought she was isolated a lot longer, like since she was a child and was given a basic education while underground.
Sort of like Brendan Fraiser in that movie where his parents raised him in a fallout shelter for 30 years until he was released.
Overall, though, find the show fun and will continue with it.
