De Palma's second film about psychic powers features a stellar cast including John Cassavetes and Kirk Douglas, and some spectacular sequences, but fails due to a silly and muddled plot. A few scenes are particularly memorable, like the amusement park scene, but the entire middle section of the movie lags, setting up a rather unsatisfying finale. Douglas is excellent as usual, and Cassavetes plays the best cold De Palma villain this side of John Lithgow. Signs of a talented filmmaker are here, which De Palma would finally pull together a few years later to make "Dressed to Kill" and "Blow Out", both of which are vastly superior movies. Despite it's strengths, nothing really adds up to a satisfying film experience.
