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.
