I found it strange as well.

I found the movie rather odd, but compelling

One of the "real" horrors of the film seems to be puberty - all of the kids in their own ways are confused about changing bodies, stuck in an awkward transitional phase they don't know how to deal with (manifested as actual loss of motor control, among other things). The adults, too, don't know how to handle it, and one of the tensions of the film is that gap in understanding and communication between parent and child.
