@My_Goldfish_Held_Hostage, I think Coco was made largely to express Velma's interest in women, and Velma's interest in Coco was I think a big talking point of the creators of the movie. If I remember correctly anyhow. I just...wish the movie did more with the relationship of Coco and Velma. For how talked about Velma's interest in Coco was I unfortunately wasn't satisfied. Though at least fan-artists did heavy lifting with them. I hope we see Coco again one day, especially since Coco has a great design.
Also as for the Mystery Inc series there's interesting elements about it, but for me it was too depressing. As it's basically a H.P. Lovecraft story with Scooby Doo characters. I know a lot of people really enjoyed the series, and say more power to anyone that does. For myself I prefer when the IP is just some casual comfort food haha
