I can't give 4.5 stars so I'm rounding up. 9/10.
This show is really good if you are a fan of the games. I can't give a perspective from someone new to the Fallout world (nor will I try), but as a ex-gamer that grew up on Fallout (I'm too old now and don't have time to play video games), I thought it was really, really good. Lots of memories came flowing back watching it and the show kept me engaged and interested. Character development and story were based on cliches, but the series made it work because of the setting, writing and excellent acting. I will be recommending this to my friends and family but based on the reviews, I'm sure they are aware or watched already. Congrats to Amazon Prime, Bethesda, J. Nolan and all the cast, crew , writers, etc for an amazing ride. Thank you!
