The show is over, and all the issues seem to be resolved. Or most of them at least. It was not a bad show, but I think it could have been better. In the end, it lacked "teeth". Or "edge" if you will.
They could have lean in more into psychological aspects of the characters, use darker tones. Moments that should have felt "heavy" felt relatively shallow, with their weight being told, rather than shown most of the time. It's not like you would not get the importance of those moments, but resulting resolution did not feel as satisfying, because it did not feel like there was an obstacle to begin with. Even though, on paper, characters did have serious issues, that they needed to overcome.
The racing was also lackluster. When there was any racing, that is. I am personally not that much into racing, but I know that it can be nerve-racking. It can push you into the back of your seat, even if you are just watching. Here the races were more like a showcase how good the studio can animate the cars, there was no excitement in there.
Still, overall, the show was not bad, I did learn a few things about races (no idea if I will remember them, though), but I think it should have been a movie instead. Maybe 2 hours long. It should be possible to edit it in a way that would improve overall pacing, and maybe that could, in turn, make it more exciting.
