This is an absolutely incredible movie, but it has enough mystery elements to it that you're best off not knowing too much about it before you see it. Christopher Nolan has once again shown himself to be one of the best directors in the business. On the other hand, IMAX is definitely not worth an extra $4 per ticket, especially with the faux-IMAX screens that are being rolled out all over the country. The screen is a bit bigger, the picture may be a little bit better, and the sound is louder, so much so that any improvement in sound *quality* is imperceptible.
