I am seeing it in IMAX 3D HFR. Why? Mainly because this marks the first film ever to potentially make good use of 3D by updating the industry standard of 24fps to 48fps. Avatar 3D was OK, but my eyes got fatigued by the judder in the panning, and various sequences where there was a lot to focus on, with the limitation of 24fps. Furthermore, coupled with the fact that I thoroughly enjoyed the LOTR trilogy, and that I quite enjoyed the visuals of Avatar (despite a rather poor attempt of a story etc), I felt The Hobbit could potentially be the best movie in a long time to really change the way we experience films. Taking a stellar story such as the Hobbit and using the foundations laid by Avatar for 3D, and further improving it with 48fps, I just thought this could be an experience unlike any other.
Sure it could suck balls in 3D HFR, and if it does I will just view it again in normal 2D. I just felt it would be dumb for me to not take advantage of the opportunity to see it in this way, when 48fps could get dropped if it doesn't succeed. At least, I can say I've seen it.
