Anything you can slap a frilly pink dress on, a hat with ribbons, and have a tiny tea party with isn't scary. Anything that can be casually kicked across a room regardless of whether it's holding a knife is not scary. Are those porcelain eyes creeping you out because they follow you around a room? A ball-peen hammer can solve that.
Nothing that can be defeated by a ball peen hammer can ever be scary. Or anything that can be taken out using the phrase "shaken repeatedly by a dachshund."
Also, go ahead and Google all those movie titles to make sure I didn't make any up. I'll wait.
So, let's look at one of the only things featuring puppets I've ever actually liked: a bizarre little anime called Puppet Princess.
Just a heads up: there are some screenshots with blood, but I made sure to censor the screenshot showing a bare butt. Read at your own risk (and you probably shouldn't do it at work). This film is rated R.
