To be honest, I don’t know how you could review this show any less than a 4.
The cast is star-studded and they don’t let down. Acting is phenomenal. Writing is clever and honest. Pacing is fantastic.
The only real issue I have with the show is that the caricatures of Texans are a little corny at times. But such a scene occurs once every 3 episodes at best.
The only other bad reviews are from engineers who didn’t like the realism of the show. I think they need to be reminded it’s a TV show, not a documentary.
