“The Babysitter: Killer Queen” (** out of four) was a strained sequel to the surprise 2017 hit about the continuing misadventures of Cole (Judah Lewis) who survived a satanic blood cult and now has to embark on the even more dangerous ground of attending high school but the physical and personal demons from his past soon return and he has to find creative ways to fight them off. Director McG directs with his usual flamboyance and panache and throws in some homages to earlier teen classics (with a nod to “Risky Business”) and some great soundtrack selections (yes the Queen title track) but it’s a lot of energy expended over nothing, since the story is practically nonexistent. Only for die-hard fans of the original.
