This series is the example of how to bring an old property to a new audience without forgetting what made the source material great in the first time, unlike other attempts to reboot the Harvey properties like Casper's scare school, Harvey street kids makes a good work at modernizing the classic characters and balancing new ideas and characters with the classic property.
The three protagonists were redeigned and rewritten but still remind the character they used to be and we used to love, the animations is nice and colorful and the character designs keep some elements from the comics' talking about that there are some references to Harvey comics that only old fans will understand.
The new characters are funny, the stories are simple but entertaining, I would recomend the show to both, fans of the Classic Harvey comic books and people that like modern cartoons like The Loud House.
