An oddball of a youngster gets bullied by various people until he reaches his breaking point.
There’s an argument to be made that The Weirdo isn’t a horror movie at all. It’s a revenge movie, and not a very good one at that. The concept has been used many times much more effective, touching, gruesome, shocking – you name it – way, and served in a visually more splashy fashion.
Only interesting aspect in The Weirdo is how the main character is just not simple innocent victim, but like many outcasts he can also be bit of an asshole, even towards the people that care for him.
