The acting was mediocre. The main actor playing the young Harley does an okay job, but the character he plays lacks some considerable common sense. His mother, is also okay, but the generic "I'm trying to keep everything together" mom. His older brother Austin, I disliked because every line he said sounded like he was whining constantly.
This is kind of where the story falls flat on its face. When the animatronics go on their killing spree, there isn't any kind of emotional output from the characters. It's as if they're bored of the idea of getting gruesomely killed by robots. You can't really bring yourself to care about any of the characters which is one of the many traits that horror movies suffer from. The writing was also predictable, and did not try to do anything new.
I can't honestly say that I can recommend the film because while it isn't bad, it's nothing that's any different from your standard slasher films but this time, it includes Hana Barbara characters. But if you are intrigued by the idea of a movie subverting childhood shows, by all means give it a watch. It is bile fascination at its finest.
