Honestly, I am an 18-year-old college student and I think this show is pretty entertaining to watch. I know this show is meant to aimed at young children at the age of 2-7 years old but I have to admit even for kids show it is not that bad. If you are in a stress full mood or if you have had a bad day this show might help.
It is even better than the idiotic shows what Cartoon Network force feeds kids with nowadays like Teen Titans Go! which teaches kids stupid lessons. Avoid that show and watch this instead if your kid is interested in space, rockets, and stars then you have come to the right place.
I don't keep regular updates with this show either since I am more into action shows like Star Wars, Marvel, TMNT and DC. I only watched 3 episodes because they were in my YouTube recommendations.
The CGI animation is decent and the voice acting especially Hawks is very funny even though as I have mentioned on my Yo Kai Watch review that Mark Risley should stop milking down the same voice actors for every episode and also hired voice actors like Dee Bradley Baker, Nolan North, Kevin Michael Richardson and Tara Strong to voice in episodes. But apart from that silly drawback Space Racers is a pretty decent show.
Not that long ago I made some fan fiction of Spiderman the animated series (1994) which involved Space Racers and for some random reason Hawk reminds me of Peter Paker/Spiderman from the 1994 TV show.
But my favorite Space Racer is possibly Eagle.
As I have mentioned before if your kid is interested in Space and has a dream to become an Astronaut, build rockets or even go into space then I would give this show a go. You never know even older people could learn a thing or two about space which might have been not covered properly basically you watch, learn and have a laugh here and there. On top of that it has good messages for kids like what can teamwork and friendship accomplish.
