Saw it and enjoyed it, though I wished I had attended a 2-D screening (I can't see 3-D due to my left eye, but my friends all wanted to see it in 3-D so that's the screening I attended).
One thing not getting enough attention is the SOUND. They really made great use of directional sound, and not in a gimmicky way. I liked the movie a lot, not sure how it would stand up to repeated viewings, but it's definitely worth seeing theatrically as opposed to waiting for Blu Ray. The incredible size of everything is much better conveyed on the big screen and will certainly lose impact no matter how big your home screen is.
