In my honest opinion, then the 2012 "Scooby-Doo! Music of the Vampire" animated movie wasn't the brightest of moments in the Scooby-Doo franchise. Why is that? Well, personally I didn't care much for the musical element that was introduced here. It was just forced and didn't really have a natural place in the cartoon that various characters would spontaneously break out into song in often odd moments.
Without going too deep into the storyline, I will just briefly summarize it here. Scooby-Doo and the gang go to Little Bat village for a vacation after their last solved mystery, as Velma wants to visit the local Vampire Festival. Meeting up with Vincent Van Helsing, what was supposed to be a quiet vacation turns into another mystery as it turns out that some vampire imitators summon forth an ancient vampire by the name of Valdronya.
It should be said that the storyline was good, and the storyline itself was actually quite up to level with other animated Scooby-Doo movies. But it was just a shame that it was cut short by the musical elements.
The animation and drawing style in the cartoon was good, and it had that unique Scooby-Doo feeling that we all love. And being an animated movie, then the voice acting is alpha and omega, and I will say that the talents they had on for the voice acting was good, and they were doing great jobs with their respective characters. It is always a treat to have Matthew Lillard voicing Shaggy and Frank Welker voicing Scooby-Doo.
"Scooby-Doo! Music of the Vampire" certainly does have a place in the Scooby-Doo franchise, but it just wasn't one of the stronger pillars in the franchise.
