This review is not about the DVD or Blu-ray, it's about the film itself. I received an Amazon Instant Video rental of the 2006 remake free when I bought a Blu-ray of the original 1976 classic with Gregory Peck and Lee Remick from Amazon . . . a welcome feature they offer free with the purchase of many of their Blu-rays. Was a bit puzzled at first and a quick search of Amazon revealed they do not have the 1976 version in their Instant Video catalog, only the 2006 remake. Viewed it streamed to my (modest) home theater Blu-ray player and 46" 1080p HDTV. I have a very high speed connection and home network; viewing was not quite as crisp as a well done Blu-ray, but better looking with less noticeable compression than my local Comcast cable service would deliver, and certainly much better than a DVD (even with the player's upscaling). So much for the technical aspects, for which I'd give it 4.5 stars.
This gets 3 stars because this 2006 remake is not up to the level of suspense and palpable tension generated and delivered by the original 1976. I would be wondering why bothering to remake The Omen, except it's obvious as with other recent remakes (e.g. Psycho) that the producers and studios are hoping to turn profits on them by leveraging on the reputations of the original classics. The Omen was not adapted from any novel or short story (the novel was written from the screenplay and released just before the original film for marketing the film). This remake is, at best, an "update" with near zero revision of the original screenplay incorporating the current technologies of personal laptop computers, cell phones, etc. Overall it's a solid workman-like product without any serious flaws, but it doesn't emotionally deliver the sense of horror and dread the original does, even now, as I've also viewed the original again, after seeing this one. The acting of Liev Schreiber (Ambassador Thorn) and Julia Stiles (Mrs. Thorn) is good, but it's not the chemistry or level of Peck and Remick. There's no comparison between the two Damien's. The 2006 iteration leaves much to be desired as he clearly does not have or express near the evil ominousness of the 1976 Damien. Was it the casting, directing, or a combination of the two? How the 2006 actor delivers in future films will tell. The one standout is the nanny, Mrs. Blaylock, played by Mia Farrow. Her facial expressions, mannerisms and dialog delivery very clearly portray the evil ominousness Damien lacks. Remaking or updating a standout classic is high risk for everyone, the studio, producers, actors and director(s). In this one, they did not fail (other than Damien IMHO), but they clearly did not rise to nearly the level of the original, which is sad. Even without the original to compare and contrast, this film would never have garnered any Academy, BAFTA or Golden Globe nominations, but it would have fared OK in its genre with mixed to mildly positive critical response. It's the presence and comparative power of the original that has justifiably generated the mildly negative critical response to the remake.
See the original, and if you're going to buy one, buy the original, it's better overall. Rent this one for a rainy night and appreciate Mia Farrow's nanny portrayal.
