OKAY SO OMEN II AND III. What's interesting about the sequels is that while both are pretty blah, the reasons they both fail to be a proper sequel to the original are pretty different. The failure of the Omen II is pretty simple, but there's some intriguing things going on with the The Omen III.
There's a pretty constant series of events in The Omen II that play over and over again. Damien is a teenager, his adoptive uncle refuses to listen to things, people present obstacles to Damien and/or the satanic plan and die shortly after. Initially, Damien isn't aware of his ancestry, and really doesn't seem that sinister, just your average jerk kid in a military academy who happens to give rise to his anger by making people hit their heads against the wall. It's a minor plot complaint, but it kind of fucks up the great ending of the original, what with the SINISTER AS FUCK SMILE implying that Damien is starting to figure things out. Instead, for most of the movie Damien is just bewildered as fuck, like being the Antichrist is something the pamphlets fail to mention about puberty. Fortunately, Damien has a young Lance Henriksen, playing the head of his unit, to teach him the ropes. Aside from my man-crush on Henrikson, objectively Henriksen is one of the better parts of the film, being creepy as shit and probably the closest thing to the atmosphere from the original.
Really though, the problem with the film is the sheer repetition, especially in death scenes. Say what I will about the original, it knew how to come out of left field multiple times and surprise you in how people were going to be offed. One of the more infamous scenes is the PLATE GLASS death. It's the Ur-Final Destination style of death, a Rube Goldberg series of unfortunate angles ruining your day. It works because at this point in the movie, you know what the result is going to be, but HOLY SHIT DID YOU SEE THAT process. It obviously wowed the producer of the sequel, as his plan for the film could be summarized as "the plate glass scene, seven more times."
By the end of the film, it's literally ridiculous in how every death scene functions essentially the same way:
1) An Ominous Crow and Latin Chorus Appear!
2) Victim casts Does Normal Thing!
3) Latin Chorus began to sing!
4) Crow Casts Really Inconceivable Series of Events! Critical Hit!
5) Victim Died!
It is literally the 70's Final Destination, which wouldn't be so bad if the Omen II wasn't trying to take itself so seriously. It's hard to be be really brought into a terrifying world of the devil when you're going "oh shit bro it's that crow and hey is that latin haven't heard that before what's going to happen" every five minutes. To be fair, there's some really good death scenes, especially by 70's standards, but the essential point remains. The only time a possessed box doesn't fall on a player's head is the end, which really wants to emulate the original's ending, and ends up rivaling the ending to An American Werewolf in London for making you feel like the screenwriter had five minutes before filming to come up with the ending. It is the quidessential "what, what" ending.
Though Omen II had better death scenes, Omen III is probably the better movie. There's at least a sort of plot progression, as opposed to demonic wheel-spinning. Damien is now Sam O'Neill, head of a giant multinational corporation, and after his Rottweiler that can growl at people and control their minds takes care of business, the American ambassador to Britain. Yeah, did you notice something odd about that sentence? While Omen II was a misguided attempt to emulate the original, the third time around is an exercise in utter insanity. It doesn't help that there are three sort of intersecting plots, none of which get enough screen time to really flesh out. There's the usual two "Damien being bad and getting badder," and "person close to Damien (this time, a female news host) discovers he's not a cool bro," but now there's a plot about a group of monks (presumably Benedictine, as they meet in Subiaco) who have gotten the magic daggers to kill Damien and utterly fail in every way (again, Benedictines, which was really baffling because I cannot think of a monastic order less suited to doing something besides drinking). The added element just means that the movie is more complicated, but more insubstantial. There's alot of subplots within the main plots which get maybe ten minutes of discussion, such as the whole issue of the news host's son becoming an acolyte for Damien. There's no slow degeneration, it's pretty much a jump from "wow mom damien is pretty cool" to "HAIL SATAN BLOOD FOR THE NEW FLESH."
Simply put, this movie is pretty insane. It might be that the screenwriter was trying to invoke the whole Revelations vibe, but the tone is like the dullest fever dream ever. By that, I mean while there's lots of weird stuff going on, the reaction to it is usually just "Really? Really?" This especially applies to the ending, which is just pretty embarrassing on all counts.
One thing worth discussing is the portrayal of the Antichrist here. Generally speaking, horror movies tend to portray the Antichrist/Devil as a sort of super powered, smooth operator baddy that tempts people, or just a generally murderous destroyer without much personality. Sam O'Neill does neither. Here, the Antichrist is essentially a portrait of the Devil by Woody Allen.
- As a business leader, he's obviously mean, but he's also fairly incompetent. His big political conspiracy plan essentially explodes in his face. More importantly, when Christ finally comes back, he just bones up everything completely. He's essentially convinced that Christ is coming back as a baby due to some Apocrypha text, apparently completely forgetting that Revelations essentially states that Jesus is coming back as a FULL GROWN MAN. He assigns the job of monitoring the destruction of all babies born at that time to the guy whose wife JUST HAD A BABY, and doesn't really pursue the possibility that the baby might be included in the whole thing until he's pretty much told that that's the case.
- Even in public, he's sort of awkward and weird. He has less the aura of something that seduces and destroys and more of someone who reads pickup artist forums. This is especially apparent during his scenes with a Jesus statue that is bending over on the cross. I couldn't tell if the scene was there to make us sympathize with Damien, or just feel embarrassed for him him as he rants about how Jesus is totally square and the devil just wants to have fun in tormenting people in this weird way that's basically the opposite of Al Pacino's scenery chewing rant.
- Did I mention the bent over jesus thing? Probably the most baffling scene in the movie is when he decides to buttrape the news lady, who finds him in the morning lying naked next to the christ statue. What.
