I watched it on IMAX 3D - - if you want the 'loudest' and 'largest screen' experience, then it will be worth it in my opinion.

But note that the 3D is somewhat lacking (e.g. compared to 3D animated films) but does add a bit more depth.

Also... large a** subtitles covering the bottom 30% of the screen. Thank you multi language subtitle local cinemas.

yeah, the stupid large subtitle is a major turn off, especially for IMAX 3D, very distracting
