Some quotes from critics:
"done with mood and style by director John Moore (Behind Enemy Lines), who knows that the story itself is engrossing enough that we don't need 'X-Men' stuff in the visuals"
–Roger Ebert, 2006
"On every level, The Omen isn't just bad filmmaking, it's bad storytelling. "
–James Berardinelli, 2006
