This one was quite possibly my favorite episode yet!
Everything was so well executed in this episode, and all the previous issues I've had with episodes are gone. Fred, Velma and Daphne felt like they had more personalities in this episode. Velma's excitement to be Sherlock's Watson was sooo cute, and I liked seeing Daphne's quirkier side from Be Cool again here. I felt like they experimented a bit more here with the characterization and plot, which was refreshing to see along with the still-classic vibes the episode gave off.
The Screaming Skulls were excellent villains, and I admittedly only had guessed that they were the Beefeater, not that it was both people the gang met. I also really liked the guest, Sherlock Holmes. It reminded me a lot of Don Knotts acting as Homer Pipsqueak in "Guess Who's Knott Coming to Dinner?" from The New Scooby-Doo Movies. Sherlock turning out to be just a lonely old man was sweet, and I'm glad they stuck the message in there about not caring what others think of you at the end. It's a very important self-love message that I think we forget sometimes in this culture of social media and insecurity. I'm glad they are putting these types of messages in here for the kids!
Also, did anyone else think that Shaggy's shirt turning red in Sherlock's lab was a reference to his 80s self?
Overall, amazing episode and I'm really hoping that this is indicative of how future episodes will be!
