I saw this movie in both 3D and 2D, so here's the verdict. 2D was "worlds" better. There's simply no comparison. And here's why: Part of what makes Avatar such a neat movie, is the colors. The rich, brilliant, and vibrant colors that Cameron chose, envoke fantasy and believability in the minds of those in the audience, and were nothing short of breathtaking. As cheesy as that sounds, there's no joke in that statement. The colors were EVERYTHING in this movie. Let me ask you a question: If you were driving through Paris for the first time during the daytime and your car's windows were tinted, would you drive through Paris with your tinted windows rolled down? or tinted windows rolled up? Assuming you're inclined to appreciate Paris, would you prefer to behold Paris in its natural colors, or tinted colors? Do you prefer your colors to be full and alive, or dull, flat, and tinted? ... 'cause that's what 3D glasses will do to your movie experience... eliminate precious lights and colors that are pivotal to maximizing your Avatar experience, or any CGI movie for that matter. In Conclusion: Seeing Avatar in 3D, is like watching it through tinted windows. The colors, and the digital cinematography of Pandora(their Earth), will look like SCH1T through 3D glasses. There are several companies that manufacture 3D glasses... I've seen movies through most of them since I'm in traveling sales. The absolute WORST 3D glasses maker, is by far Dolby Digital. Their glasses are the most tinted above any other, and are TERRIBLE for watching anything CGI. Don't believe me? Go ahead and waste your money on a worthless premium. I guarantee your movie experience will ultimately be much better seeing Avatar through the naked eye!!!
