I saw it in glorious 2D. There were several scenes that one could see were "doctored" up to be just made for 3D.
I carry several conditions from a happening several decades back. One of the conditions is vision triggered vertigo followed by a neat hit of nausea and sometimes , projectile vomiting. One of the things that triggers my loss of luncheon is 3-D and really rapid screen focus movements. (The only ones of rapid screen focus movement that I can recall right now is from the old 70's movie BULLIT and that space opera with Ms Bullock and Mr Clooney where they are tumbling in space several times in the flick)
There was a scene from 6th Sense that was borderline.
I cant physically take 3D, but I can see where the picture was loading up for such a shot so I could , probably, just close one eye.
To me, it was the same thing that made AVATAR a lame movie for me. They just loaded up the special effects and 3D qnd IMAX and IMHO, the movie story was lost (not so much lost as "covered up" by dragging it out with CGI for its own sake)
Jungle Book, actually , didnt need two things that they insisted on including
1 the dumass songs that were dug up and rewrapped from the original Disney cartoon (those songs actually evoked a whhhaaaaaaa? from Mrs F and I)
2. The 3d "leaders" , As I said above, It reminded me of the COUNT FLOYD and his 3D (John Candy did this routine goofing on old 3D movies) during his appearances with Count Floyd on "Second City TV"
I woulda said that the movie didnt need King Looie, but with Walken voicing the role, it was a great goof on the whole Disney attempt to be Darker with this one.
