Like a good caper film, the safe to crack is Silver. The loot, proving he's a fraud. Cortés gives us stakeout scenes, races against the clock and double and triple twists. Weaver and Murphy spend many a scene using their tech to 'scientifically' (movie science) and publically expose a variety of paranormal frauds. Cortés nicely weaves and builds suspense through these moments then juxtaposes them with philosophical debates between science and the supernatural interspersed with collegiate battles over financial backing for their projects.
Unfortunately the film sidesteps into more gimmicky and traditional supernatural schlock, while exciting in many horror movies, feels obtrusive and unnecessary here.
