Finished the show right now. It's definitely worth the watch. I mean, the show is definitely on the same caliper as movies as Rush or Ford vs Ferrari, speaking in production quality terms.
What differs them is mainly the cast, as several abroad folks will miss big (BIG) names, and the not so big focus on the races part. Not that the races were poorly done, they used real cars, and real circuits with doubles racing real laps and, for some scenes, they faithfully recreated the circuits using Unreal Engine. But races just deserved some more screen time.
Even if most of the cast is unknown overseas, the characterization is fenomenal. Everybody who used to watch Formula 1 will immediately relate to the face of Prost, Xuxa is also amazingly done by the actress, and the Senna actor did a great job representing him, it was a pleasant surprise.
If you are still having second thoughts if it's worth your time, watch the making of first, as the story itself is not secret to anybody, it will help you decide if you wanna see through or not. Also, if you're worried that Netflix ruined the show somehow with some politics takes, worry no more. There's just one character that was fictionalized, a journalist that is played by Kaya Scodelario. It wasn't done in bad taste, as it's just like the Chernobyl's Ulana Khomyuk, a single character written to embody several people who, somehow, were present on the main character's life.
