Patrick Channing (Jeff Kober) is a disciple of Satan / serial killer who possesses the "First Power": even after being captured by detective Russell Logan (Lou Diamond Phillips) and executed in the gas chamber, he is able to move his spirit from body to body and continue to murder at will. With the help of attractive psychic Tess Seaton (Tracy Griffith, Melanie G.'s half-sister) he attempts to stop Channing.
This concept probably had some possibilities, I think, but ultimately "The First Power" suffers from routine scripting and film-making. This is nothing we haven't seen before, sometimes done better. There is nothing about this movie to distinguish it from other supernatural horror thrillers. More to the point, it's not very thrilling and it certainly isn't scary. Phillips is a hard sell as a tough-as-nails, cynical cop stereotype, and Griffith doesn't seem to be trying very hard; best cast member is probably the distinctively featured Kober, doing his best to be supremely creepy.
The climax is rather silly and the ending very weak.
Not really even acceptable enough to rate as an average film of its kind, therefore:
4/10
