It is funny to me how much people seem to want to hate 3D without ever seeing a proper demo.
To me, that would be like me deciding if I want a surround sound home theater system based solely on a Bose Lifestyle system.
I think that there are certainly pros/cons to anything. But some people only want to see the negative.
Here are some facts/opinions based on my experience with 3D since my upgrade in April.
Can a properly setup 3D system produce outstanding results > YES
Would I want to watch everything in 3D, all the time > NO
Does choosing a 3D projector/TV/ display cause you to sacrifice your 2D image > NO
Can you get a 3D setup with ZERO Ghosting > YES
Can you get 3D without any flicker from active glasses > YES
Can 3D if done properly add to a movies experience > YES
The number one complaint I hear out of people is they dont want to wear glasses. That seems the same to me as someone not willing to own a great pair of speakers cause they wouldnt want anything taking up floor space so they opt for in-ceiling speakers. Meaning there is a trade off to just about everything. Maybe this isnt a big deal to me because I already wear glasses for watching tv. I think if anything it should be more aggravating to have to wear 3D glasses over glasses then just to wear 3D glasses. I hope to see prescription 3D active glasses soon. I would pay anything for a good pair.
I have probably shown 3D in my theater to atleast 100 people since last April. 95% would say it is the very best 3D image they have ever seen and are left wanting 3D, even when first asked about it they said they were not interested. There is still 5% who either dont care for 3D or just for whatever reason cant see a big difference.
I know that I have the very best 3D image I have ever seen. (maybe excluding Peter's Barco setup at cedia

) I have watched 3D at many many theaters and never have had the same experience. Mainly beacuse most are way to dim and there is still a decent amount of ghosting. I wish my 3D image was as bright as my 2D image, but when watching a 3D movie with either my screen set at a 14' wide scope or a 12' wide 16:9 it is still plenty bright at about 13fl. I get ZERO ghosting since I changed out my Xpand glasses to the RealD CE4. The Xpand X101 glasses are CRAP! You do not have to sacrifice a large image or replace a low gain AT screen for great 3D, you just need to select an appropriate projector with the necessary brightness. Preferably one that is dual lamp and you can vary the lamp brightness so to balance 2D and 3D.
I absolutely enjoy every 3D movie I watch in my theater, some better than other but they all do make me feel far more immersed into the movie. The most frustrating part of 3D is having to learn as you go. Alot of times there are gliches and it takes alot of time to get the setting just perfect. Certainly many hours of trial and error. But the results have been well worth the effort.
If we can just get full-res 3D for live events from DirecTv it would be perfect. The reduction in resolution for those sources hopefully will be a thing of the past before to long.
