It is quite obvious that the Senna - Da Silva family had a hand in this, and a very strict one at that. Senna is described as a saint. He's always kind and nice and puts up with everything that's done to him. That's boring and superficial. There are no conflicts except with Prost and Balestre.
The dialog is so incredibly flat, any daily soap is literature by comparison. I want to be first. He's the best. I'm the fastest. I want to win. But that's dangerous! But I want to win. But you've already won. But I want to win again.
What about Senna's women's stories? That would have had potential. Didn't he have any vices? People like that don't exist. But when his mother is involved in writing the script ...
His parents also come across as saints. Always understanding, always patient, kind, indulgent and noble. Yes, of course.
The action pictures are top-notch, though. Not completely groundbreaking, but very impressive. Especially the sound design was awesome.
