Remakes have a responsibility to remain faithful to the source material!
I grew up watching Scooby Doo in the early eighties so I am mildly disappointed in this remake. The Scooby Doo shows started in 1969 and new animated shows were produced for twenty years. This means that there are probably grandparents who could sit down with the whole family to watch this reboot. I would consider this to be an affront to long-time fans in the way they have
presented alternative versions of the original characters. There is an existing audience of Scooby Doo fans who will be alienated by this show and I do not plan to watch the show.
Fred was the heroic white male leader of the team and he is now a feckless white male who will probably come out as gay. Daphne was the pretty red-headed white lady who is now a red-headed Asian drug dealer with two lesbian parents. Shaggy was a white comic relief character voiced by Casey Kasem and he is now a black male character using Shaggy's original name Norville. Velma was the white female nerd who used her intellect to solve cases and she is now an Indian superfemale voiced by Mindy Kaling. It's also odd that Scooby Doo hasn't appeared yet BUT I predict that he will be a pit bull that raps and smokes weed.
Many of these animated tv shows in the eighties were vehicles used to sell various types of merchandise and toys. The studio is damaging the Scooby Doo brand by releasing a bastardized remake. This show could generate more merchandise sales from multiple generations but many long-term fans won't bother buying merchandise with the new crew of misfits.
The original characters brought their strengths to the team BUT it seems like Velma is the only strong character in the show. The original Scooby Doo shows were kids' shows while this show has gore, drugs, penis jokes and lesbian kisses. I support jobs for BIPOC actors but I would rather see them come up with new original shows. Another approach would have been to introduce Velma's BIPOC friends from the science club who would work with her on cases.
My overall position is that significant/iconic cultural, historical and religious characters should not be race-swapped or gender-swapped AND their portrayals should remain faithful to the original source material. Fred Jones in Velma was not race-swapped BUT he was transformed from a hero to a ZERO.
