To each their own. The two worst 3D methods in my opinion are anaglyph (red/blue), and the Pulfrich system (using movement). With the r/b system, you have to almost consciously focus (or rather "relax" your focus) to get the best effect. This can be very hard on the eyes. The R/B method (as with any 3D system) must adhere to strict tolerances from filming to projection. Any "weak link" in the production of 3D (position of the viewer with respect to the projected image, a poorly focused projector, a print of the film with less than accurate color, "non level" viewing or projecting the images, etc.) can lessen the 3D effect, or further contribute eye strain.
I'd have to side with the guy saying that the polarized method is my preferred method but it is also not without problems (mostly eyestrain).

| Time to get detailed here. Why not? I've been wondering about this for a while. What do polarized projection lenses do that prevent proper replication on a CRT? |
Direct view televisions (including LCD & Plasma Screens) cannot split the video into two different polarized images, (one for each eye) and project them simultaneously. I'm unsure if a projection TV (front or rear) can project polarized light, there would have to be double the CRT's (one Red, Blue & Green CRT to project a polarized image for each eye). This would contribute to increased complexity as well as a huge cost increase to the set. Remember that the polarized method also cuts available light, making the far movie dimmer (anyone remember "Space Hunter" or "MetalStorm"?), I just can't see where a projection TV will be capable of polarized 3D anytime in the foreseeable future.
Some DTV sets have an "interlaced mode", which would allow them to work with the LCD "sequential view" or "shutter glasses", and such 3D systems would work well with direct view television (LCD and Plasma displays do not interlace so they won't work).

You are correct. All your DVD player sees is code, all your TV sees is a picture. The red/blue is encoded as part of the image, and requires no additional processing so it works on all "properly calibrated" displays.
Also consider that there is a reason that 3D has not caught on in the past. Most 3D movies (excluding IMAX) have been light on story, and heavy on crap coming off of the screen toward you. I found that while watching Friday the 13th part 3-D, the sense of depth was fantastic (even better then when things were coming off of the screen)! I also think that the 3 dimensional depth worked well when they faded between scenes as one scene seemed to "come up" from behind! Unfortunately, due to the polarized method, I couldn't properly snuggle with my girlfriend at the time. You see, tilting your head, offsets the polarized glasses from the polarized projection, so things get fuzzy.
I'm no expert, just a 3D enthusiast. I'm considering selling off my sequential view "shutter glasses" with the few DVDs that came with them as they don't work well with my HD set. So far as affordable "in home" technology can provide, red/blue anaglyph is the easiest, least costly way to go. Just make sure that you've got your display's color calibrated, and convergence set up correctly to eliminate any weak links in the chain.

As for Spy Kids 3D? I thought it the story and 90 percent of the acting was lame as hell. The 3D effect however was pretty good (not great... for great, go to an IMAX 3D film). I'd love 3D to continue to catch on.
