The low framerate (24fps) became very noticeable for foreground objects for me, I think because their apparent velocity caused insufficient overlap between successive images. But I haven't noticed this in conventional movies - was it due to 3D, or was the shot chosen to take advantage of 3D when it would normally be avoided? My favourite 3D sequence in Avatar was when the heroine dropped-in on her dragon, falling away from us. Very cool and effective. I think a skateboarding documentary would be awesome in 3D (or any activity that is intensely 3D from the POV of the performer).
