The Babysitter strikes me as an amusing horror-comedy that’s likely to elicit strong reactions—viewers will either embrace it or find it off-putting. I suspect The Babysitter has some significant shortcomings; the plot probably doesn’t always make perfect sense, and perhaps the characters aren't particularly complex. However, I was enjoying myself so much that these issues didn’t bother me. The movie’s comic book style graphics, surprising developments, the concept of a child genius, and the blend of humor and gore all contributed to my enjoyment. Initially, it felt like a comedy and coming-of-age story, but when it shifted toward horror, it fully committed to that genre. It maintained some of its original comedic and coming-of-age aspects, but once the horror elements appeared, there was no question that it was primarily a horror film—and an entertaining one at that. I have a feeling this will be quite divisive. Some viewers will appreciate the absurdity, while others might feel it detracts from what The Babysitter could have been. I anticipate some people will find it silly and roll their eyes, whereas others will laugh out loud and grin throughout. I suggest giving it a try, but don’t expect something serious, or you may be let down.
