The ending of the 1st Goosebumps movie seemed to imply that the Invisible Boy from the book of the same name was going to be the main villain of Goosebumps 2: Haunted Halloween.
The ending of the 1st movie had him typing on Stine's typewriter, "The Invisible Boy's Revenge"; implying that it was a sequel to not only the Goosebumps book, "The Invisible Boy"; but that it also foreshadowed that he would be the main villain of Goosebumps 2: Haunted Halloween.
I know that Slappy, the Living Dummy, was the main villain in Goosebumps 2: Haunted Halloween; but I can't help but wonder: would it have been better or more interesting if the Invisible Boy was the main villain of Goosebumps 2: Haunted Halloween? What do you think? Would the Invisible Boy have made an interesting main villain in Goosebumps 2?
