It doesn't interest me, so I've only seen Avatar and Jackass 3 in 3d (I saw something else too, but i dont remember what movie.) Both were pretty sick, but still, i dont need 3d. The awesome depth and visuals wasn't worth it when you factor in the times where shyt was blurry, or i turned my head ever so slightly and couldn't see shyt. Almost felt like i had to work a tiny bit harder to watch it, therefore i dont need it.
Actually now that i say that, its worth keeping around for the simple fact that i would have never in 100 years seen Avatar without. Tell me you can sit and watch that movie on cable, no chance. it has no replay value
