It was a pretty good horror movie for what it was. It stayed true to the lore of the five missing children, and the drawings also hinted at the lore. I also appreciated MatPat's cameo. However, I would have preferred if the cupcake killed fewer people. Other than that, it was a great movie and did not deserve the low score it received on Rotten Tomatoes.
The only thing I didn't like was how everyone kept shouting "WAS THAT THE BITE OF 87!?!?!?!?!?!?!" when the girl's head was bitten off, but I suppose that's just what the internet does to you.
