The show itself isn't necessarily "bad" but it shouldn't have been a Scooby Doo IP. It's clear this is just another show using the aesthetic of Scooby Doo for promotional reasons, there is absolutely nothing of the original source material remaining and what results feels awkward and clunky coming from these iconic characters. The main joke seems to be "haha beloved childhood character said something crass" Had they just made a new show and not lazily depended on the fame of the Scooby Doo IP this could have been a decent show. The problem isn't that Velma is brown, the problem is that Velma isn't Velma.
