Velma is a lesbian and she has a crush on a woman and isn't that empowering... it's also the majority of the plot.

And that plot is about the minority lesbian woman that Velma has a crush on showing that she is absolutely perfect, better at everything than the Scooby-Gang, and Velma has a crush on her.

One-by-one, she shows up the Scooby Gang (reminder that Velma has a lesbian crush on her) and solves the mystery (reminder that Velma has a lesbian crush on her) almost single-handedly (reminder that Velma has a lesbian crush on her) without really needing Daphne, Scooby and especially showing up Fred and Shaggy (reminder that Velma has a lesbian crush on her) and then Velma comes out that she has a crush on her...

... which was apparent and completely obvious from the start, frequently re-enforced, and the real plot of the cartoon.

I guess if you really want to teach your kids about LGBTAQ++??? politics, this is a great cartoon.

If you don't, you might want to show them something else.

I was excited that there would be a Scooby-Doo movie this year. After WBD canceled Scoob Holiday Haunt. Not only that but another Halloween movie.
The movie is getting attention just because it has gay representation. When true Scooby-Doo fans know Velma already had a girlfriend in the end of Scooby-Doo Mystery Incorporated.
As someone who saw all the movies with his nieces and looks forward to a new one every time. They started going down hill when the movies became about Velma debunking the mysteries that had real monsters “like Zombie Island or 13 Ghosts of Scooby-Doo.”
Story wise and animation wise this one takes some getting used to compared to the other movies. Since I think it is a Guess Who Scooby-Doo movie due to the same animation style. When I am not a huge fan of that show and think even the under-rated Be Cool Scooby-Doo was far superior.
Story wise it is different with Mystery Inc. bored after they capture the mastermind like Bond villain who makes all the monster costumes for the bad guys. Who’s name is Coco and who Velma has a crush on.
Halloween wise Happy Halloween Scooby-Doo was a better Halloween movie. Trick or Treat Scooby-Doo is too goofy to be one of my favorite ones. Though it does have some good music choices I admit.
They need more like Zombie Island “the first, not Return to Zombie Island”, Scooby-Doo and the Witch’s Ghost and the under-rated Goblin King one. So yeah you can say the late 90’s movies to late 2000 ones were my favorites.
