I went to rewatch it with a good memory of him but I confess that it fell a little in my vision I liked the concept of a ghost in a theater, the movie goes well until halfway through, Daphne and Fred are very much in love, Velma is always the usual Velma and Shaggy and Scooby ditto, but my criticism is that the movie gets lost in presenting characters, it must have about 15 and I know they must have thought of it to increase the mystery but there comes a point that it gets overwhelming so many people who don't even show up anymore.
my final opinion the reason the movie gets lost is to play with the revelation of the villain, I won't give spoilers but it reminds me a lot of scream, where some ghostface is caught and then there's another one loose around, I don't know if they were inspired but anyway, it's a good movie, with good concepts but that gets lost, but fun.
