Exciting: the close ups of the racing cars gets your adrenaline pumping.

Great camera work, lovely sceneries.

Flawless acting from main and supporting actors, especially HXX and WYL.

Great screenwriting as the plot wasn't spectacular but every episode was exciting filled with drama, humor, covering trauma, romance, family, teamwork, friendship, intricacies of the rally racing, and some dark sides of rally world. I appreciated that they didn't play up the dark side very much, just minor dirty tricks but was scripted well enough.

I actually rewound the exciting car race scenes a few times, especially the one where Zhendong goes "into the Zone".

Will definitely re-watch this series.
