It's funny reading some of these low star reviews, as if the people thought Fallout would be realistic comparing to today's world, complaints about the dialog, and seeming amateurish writing. I doubt they every played any Fallout video games, probably watched a few trailers.
Having played Fallout since the beginning, yes, the beginning, when the original Fallout was released in 1997. (Loved those SuperVGA Graphics..lol) I would say the Amazon Fallout TV Series is spot on! From the overuse of blood and gore to the quirky dialog.
I haven't binged watched it, I'm viewing one episode a day, to savor the experience and I'm already looking forward to Season 2...lol
