i liked it. it's like a weird 1990s/2000s period piece. a lot of the characters lives' and motivations seem somewhat plausible. idk how authentic it is with respect to life in japan, but the characters felt pretty well-done compared to most shows about that age group
i also can't help but love that they essentially ended up making a show that revolves around strategy and tactics and individuals' various strengths and weaknesses, even if most of the races are kind of fake. i'm not really into cars or japanese culture or anime, but i'm a huge fan of competitive strategy games so i found a lot to like
the eurobeat music has to be the best part though. i went and found hundreds of hours of that stuff after this show. BPM is insane. no idea if it actually works as disco/dance music or whatever its intended purpose was, but it's great for exercising
