Scooby-Doo and the Legend of the Vampire

I've been an avid Scooby fan in the last five years. Ive followed the great dane from Zombie Island to the live action movie. Now we join him at Vampire Rock. After four quite successful animated films I had high hopes for Vampire Rock. However this film is a drastic departure from those films, as Zombie Island was from the original series. There is a nod to those films present in the form of the Hex Girls and the Cyber Chase game, but thats it. The mystery machine is now the old van and Fred has his ascot back. All that the previous films had built up has gone. On the plus side Velma's orginal voice is back and sounds fantastic. Also worth a mention is the excellent reengineering of the old Scooby Doo Where Are You? incidential music. Overall the piece feels like it is pandering too much to the general populous' preception of Scooby Doo and this does stiffle the creativity. One last thing though please if there is to be another film could have Scoot Innes back as Scooby?
