No sé, pero hay bastantes críticas en Blu-ray.com o en Highdef donde hablan de un 3D perfecto.

http://www.blu-ray.com/movies/Promet...Blu-ray/39474/The 3D look of 'Prometheus' is astounding. My first experience with the latest and greatest polarized 3D was 'Monster House.' I remember sitting there with my jaw agape because, unlike the old red/blue 3D of my childhood, polarized 3D created a depth that made me feel like I was looking into a stage, not having objects unnaturally protrude from the screen toward me. (Too bad the 3D live-action films that followed it couldn't carry the 3D effect of the animated ones. From there stemmed my dislike of theatrical 3D.) Watching this 3D Blu-ray of 'Prometheus' reminded me of my 'Monster House' experience. The third dimension reaches deep into 'Prometheus,' never looking like a layered pop-up book but naturally and gradually transitioning to those great depths. It's so realistic that a few shots of the Prometheus space craft in flight are dizzying.
Prometheus 3D Blu-ray, Video Quality

And then we come to the film's use of 3D, which is some of the best I've seen outside of all-CGI movies. If you saw the 3D version of Prometheus in theaters, you'll already have a good idea of what to expect on Blu-ray, namely, lots of depth and little-to-no projection. That is, you'll spend a lot of time looking into your screen—which becomes a kind of portal through which to view a 3D diorama—but you won't find any leap-out-of-the-TV-and-jab-you-in-the-eye gimmickry, which may work in horror films or cartoons, but would only cheapen the experience here. And because there are no objects jutting out towards you, you don't have to worry about the roughly 2.39:1 frame cutting anything off. (No, there's no 1.78:1 "open-matte" version available.) There are a few longer landscape shots where no dimensionality is apparent, but most of the time there's a clear and natural-looking distinction between foreground objects and their backgrounds. There are definitely some "showpiece" 3D shots, like the landing sequence, the silica dust storm, and the engineer holograms, but the 3D effect is most impressively used to add a degree of realism to some of the more mundane scenes, like when Holloway stares into the mirror of his cabin, noticing there's something unusual in his eye. Or Shaw lying on the all-white operating table. Clarity and color both hold-up well, and there are no unusual 3D anomalies to report. Of course, the effect will be better on bigger screens—and the amount of ghosting/doubling you experience will depend on the quality of your TV/projector/glasses—but in general, Prometheus' 3D Blu-ray replicates the theatrical experience rather well.
