Stupidity: Daphne and Velma's adventure in the corridor behind the school lockers begins when they enter the theater backstage from a random door opened by a button that is lit up in the dark, effectively negating the "secret tunnel system" status. Why would anyone build a corridor with an entrance into school lockers so secret that it's invisible from the outside, and then put a button-activated entrance to it in another location, even making the button a fully lit one shining in the dark?
Stupidity: During the ghost chase montage, why would Velma look for her glasses with her hand in midair instead than on the ground? No matter how nearsighted you are, the closest wall, or obstacle, is meters away and you'll never find your glasses anywhere but the floor. She does it for a longer time than anyone would.
