Now I do think that nostalgia was a factor in how much I liked this movie but I do understand that some people won't find this as great as it could be. It was nice to see old characters like Vincent van ghoul and Flim-Flam. I could see an epic finale with the Scooby gang having to stop all the old ghosts but they didn't do that. I found the ending twist nice enough to not change my mind on the whole movie. A great way to celebrate Scooby's 50th Birthday along with Scooby doo return to zombie island.
