I could go into various details as to why this film is absolutely terrible; I could talk about the acting (or lack thereof). The stupidity of the Anti-Christ being opposed to new-age mystics (Because as we all know Satan has a particular dislike for Mystic Meg and her vague portents). The sloppy and rushed pacing and editing which leads to about zero tension throughout the film and killing any hope of creating a creepy atmosphere because scenes come and go in an instant (this is especially egregious at the start of the film where the Antichrist's first kill feels especially feeble because there is virtually no build-up at all). The addition of various sub-plots and scenes which add nothing of significance to the story and serve only to provide chills (which due to the rushed editing are very weak). And the overall fact that there is very little in the way of a goal for our heroine, she suspects that her daughter is evil but rather investigate herself she gives the task to a P.I. making her character very insignificant (couldn't they have told the whole story from the P.I.'s point-of-view?), which in turn leads to a very rushed ending with a feeble twist and a very undramatic confrontation.
All of these things condemn the film on it's own. However what really damns it is the fact that it is part of the Omen series, more to the point a sequel to Part 3, which besmirching aside, MAKES NO SENSE. The reason why it makes no sense is pretty simple; for at the ending of The Omen 3: The Final Conflict, Christ RISES AND RETURNS TO EARTH AS KING OF KINGS and Damien Thorn fails to stop him, it's not just implied, it bloody well written on the screen before the credits. Now I don't know about you but I think the literal Second Coming would be it, over, finito, THE END, the conclusion of not just the story of Damien Thorn but the end of this reality and the start of God's new reign Etc. Etc. (Pretty much as the title "The FINAL Conflict" suggests). However here apparently none of that happened, Damien just died or something and Christ had nothing to do with it. It's a complete retconing the end of the Trilogy and such leaves a sour taste in the mouth. I am aware that this is a odd nitpick but for me this film was simply a dross remake of the original until the doctor (who looks remarkably like Rob Brydon) blurted out Damien Thorn's name and cemented this films awfulness. I.e. bad as a standalone film and a HORRIBLE, nonsensical way to conclude the franchise.
