I really enjoyed the show.
A few things I think should be changed. In the first races, those that got to go first, but ended up in 3rd to 8th, got to go again with existing racers and new racers. That meant the racers who's first race was the 4th of the qualifiers, only had one go at the course, while those in the first qualifier had up to 4 races on the track.
Another thing, was that the whole event was tuned for those that could drift. The drag cars were fast, but couldn't keep up with the drifters because of the targets that had to be hit.
One obstacle was incredibly dangerous, did they not test it out first????
On the positives, it was on the edge of your seat stuff. Some of the races were so close!
All in all, it was a lot of fun. I didn't binge watch it, I wanted it too last. So I'd suggest watching it over a week to two weeks to build up the anticipation.
