“Killer Ending” (*1/2 out of four) was a slapdash, confusing murder mystery of whose ending can’t come soon enough about a best-selling writer (Emmanuelle Vaugier) whose daughter is abducted by a deranged fan who seems to be copycatting one of her recent books and her even more deranged assistant (Chelsea Hobbs) appears to be attempting to steal her identity. Hitchcock-like thriller plays like a movie he would have made in his late stages of his career, with too many characters and too many plot twists but not enough sense. Final showdown is pretty laughable, if you make it that far.
