Oddball and hyper-obscure late-80s horror flick that is perhaps not highly memorable, but at least very entertaining while it lasts. The story doesn't make much sense, but it's strangely compelling and keeps you curious. A satanist father pursues his son Daniel into an institute for troubled teenagers - where his mother hid him - and takes possession of his body. Being demonically possessed has advantages, though, as you can joyfully set bullies on fire or throw them into a woodchipper just by using telekinetic powers! There isn't much suspense, but the gore and the make-up effects are surprisingly decent, and there are reasonably good acting performances from teenage beauty Alexandra Kennedy and Linda Hamilton look-alike Twink Kaplan. I probably won't remember anything about "The Boy from Hell" in six months from now, but I wasn't bored or annoyed at any moment.
