The inventive teaser trailer drew me in, but there's not much to recommend to this prequel to the 70s-80s Horror sequence of films begun by The Omen. One or two set-pieces aside this is too drab and slow to muster much interest. The ending is preposterous and the fiery SFX sub-par. A committed performance from Nell Tiger Free makes this more watchable than it might've been and she is given superb support from Brazilian powerhouse Sonja Braga - otherwise the support is distracting with weird accents and performance choices: hello Ralph Ineson and Bill Nighy. There's a nice cameo by Charles Dance. The pregnancy scene at the halfway mark hits the mark but it's stranded inside a boring and unadventurous film. Coming a week or two behind IMMACULATE with its similar plot, the First Omen has been robbed of some of its purpose. Immaculate was crap too though imo.
