This is not the first 3D DVD or blu-ray, yet I still see reviews from people that do not understand that "good" 3D requires technology that does not yet exist in our homes. I even saw one review reference the fact that using blue and red glasses does not consitute 3D. Anaglyph 3D has existed for decades.
Anaglpyh 3D will have varied results from person to person. For example, in this film, it uses red and blue lenses where the red lens covers the left eye. Due to the wavelength of red, this means the left eye will not get any other colour information. This means the wider colour information comes in to the right eye with the blue lens. Most people have a "dominant eye", a bit like being right or left handed. If that dominant eye is your left eye, then you will likely see little or no colour other than red. If your dominant eye is your right eye, then you will get a better experience. Interestingly some blu-ray 3D movies have used magenta and green lenses, where the magenta lens is over the right eye. So this alternative scheme standard works better for those who are left-eye dominant.
It is very important when watching this film to increase the brightness setting on your display. The glasses will cause a loss of light, and you need to compensate for that. You may also find it beneficial to increase contrast as well. This will minimise ghosting and increase the 3D impact. Of course we are not dealing with videophile accuracy here...just creating an enjoyable 3D experience. Note that anaglpyh 3D can cause a level of eye strain and so you may need to stop mid-way for a break. Not compensating the TV settings first to allow for the glasses will likely increase eye strain.
It ia also important to understand that 3D immersion depends on screen size. For example, Avatar is playing at both regular cinemas and IMAX cinemas in 3D, but the 3D effect observed in the huge IMAX screen is much greater. So in the home, expect the experience to be one of greater depth with slight "out of the screen" rather than feeling something is coming out to 2 inches infront of your nose.
I have watched this through. If you understand what the movie is from the outset, a semi-horror flick with some gore and some cringe moments, and you like that kind of thing, you will enjoy it. If you are expecting some deep meaningful drama with a coherent storyline and plot, you are in the wrong place.
The 3D worked quite well on this film having adjusted the display. I felt it was one of the better anaglpyh 3D encodings so far. The image depth was maintained throughout the movie and there were quite a few moments where images popped out of the screen.
It's a harmless bit of fun, and the 3D does work for right-eye dominated people who adjust their TV settings first :)
