Ok, I don't wanna give out any "spoiler's", or anything like that. But, to me, the best part, is what Daphne does, in the episode. She does something she normally doesn't do. But, it has a twist to it, which entices the show. And, that's why it got a 9/10, instead of a 5/10. And, I get the plot behind it and all, don't get me wrong here. But, in my opinion, they needed to bring the Hex Girl's back to the episode's, than they did. I mean, to me, they are a wasted talent, with so few episode's with them in it. Personally, they should do a spin-off of the Hex Girl's, like they are on tour and have to call the Scooby gang to come help them solve mysteries, like, let's say, a mystery come's up, like a "Phantom Of The Opera" kind of theme to it, or their gear get's stolen, or something along those line's, while they go around doing concert's and private show's. While, doing a 2hr movie of them, doing a huge show, or something and turning it into a "Live Show" of the girl's. Maybe, 1/2 way through, have something come up, where the Scooby gang need's to show up, or something like that? But, that's just my opinion. They would make a killing on the DVD's/Blu-Ray's, that's for sure! Ok, enough with the Hex Girl's, who do play a significant part in the episode and do a great job, like always! Fred & Daphne are having their issue's, just as Scooby-Doo & Shaggy have their issue's, as well. Velma, has issue's in all of the other's issue's, as she play's multiple role's in each of them. And, they incorporate a blast from the past, into the name of the villain, even though the plot to the villain is a bit lame. They brought reminiscence of the old 70's "The Phantom", into the name of the villain. Along with, a 2nd blast from the past, "Vincent Van Ghoul", from the 80's "Scooby-Doo & the 13 Ghost's" series! Which, was a tribute to the late great "Vincent Price". But, in a nutshell, the plot start's out slow, but wrap's up quickly in the end. Even though, the Hex Girl's, make it well worth it, to watch it.
