1. Junior (Problem Child, 1990)
If you've ever seen Dennis then that's a fine example of how to balance an annoying child with enough cuteness to make you not want to lock him in the cellar for life. Dennis Duggan failed to hit the same balance in his 1990 stinker The Problem Child which was birthed around the same time as Home Alone. We think you're supposed to like Junior. We think you're even supposed to route for him. He's supposed to be cheeky but adorable like a naughty puppy but what he actually is is the most God awful, irritating and despised child character of all time. Hands down. If there's a more annoying child in the history of the movies, TV or even the world then please keep it away from us! Unsurprisingly Michael Oliver who played the Devilish little arse hole hasn't really appeared in anything since 1995 but that didn't stop Universal milking 2 sequels out of this horrible, universally abhorred 'classic'.
