Seen it once at the IMAX. Really want to see it again, but it's half a day to get there and back and all the decent seats are gone for at least a week, plus I've got work. Might have to see it at my crappy local cinema, but really don't want to as I loved the atmosphere at the IMAX in London, not to mention the amazing screen and sound (first time I've been to an IMAX).
