I've watched it yesterday.
I feel a little unsatisfied I would say.
Camera work was pretty good (although sometimes too much slow motion IMHO). Some stories were nice, but sometimes I've felt somehow pompous (like stories were blown or people telling them where describing as they would have bigger impact than in reality)
Although I've enjoyed history and history of racing, I think it took too much part in the movie. Together with my wife, we are riding street, track and we're dirt-courious

But I think although we love track, it's not most important aspect of motorcycling. I've got impression creators are telling me if I don't race motorcycle, then I'm not real rider.
That said I think most important aspect of riding have been missed a lot. I'm talking about all those pleasure and adventure rides. Isn't that the best feeling when you're on your motorcycle rolling through twisty, mountain rode in the woods ? It's all about you, motorcycle and the road. Or don't we love to take unknown road and see how it would turn out ? Meet with the different characters as we travel far far from home ? I've missed that aspect a lot in that movie and that's my biggest disappointment.
I've also missed somehow part about dangers of riding. I understand creators probably didn't want to scare people of motorcycling. However I think they could mention dangers lightly and show how people protects them from the worst. Pretending dangers don't exist, doesn't make them disappear
Another thing missing was working on the machine. Although they mentioned some restorations done by families it didn't show any aspect we've discussed lately in this
thread.
All and all I'm left with mixed feelings varying from disappointment to mediocre.
