Gist is that this sort of idiot played by Adam Sandler named Hubie Dubois, sweet guy, like fucking lives for Halloween in his hometown of Salem, which he fucking loves the shit out of. Yeah, he gets bullied constantly. Slowly, those bullies start to disappear. Foul play is indeed going down though Hubie suspects there is a supernatural element at play. Hubie shares a lot of DNA with Bobby Boucher from The Water Boy. Same voice and demeanor. Basically a lovable idiot.
Ok. Quick bone to pick. I usually don't pick a whole lot of nits, but after Hubie saves the day at the end, we cut to a year later. Hubie is now the mayor of Salem. That means that he would have had to get elected the previous year, like a week after most of the movie goes down. Pretty sure that he would have already had to do a bunch of stuff to get on the ballot at that point with early voting and all. Plus he no time to campaign. Must have been one hell of a write-in situation. But, yeah, not really the point of the movie, I guess.
For me, the MVP of the movie was Salem. I'm totes going there for Halloween some year. Town really gets into it with its history and everything. Looks to have a carnival-type atmosphere. They know how to do it up.
