I had a couple Eyegasams watching it. Story was alright, was predictable as most movies now days but it was not horrid, not like the Transformers movies. The 3D blew me away, sure as hell this will change movies and the way you experience it from now on.
I do suggest, if you have not seen it yet, sit at least 8-10 rows back. If you have the chance, see it in IMAX for the best experience.
