I was this twice,the 1st time was in 3D at my local theatre and the 2nd time was at the IMAX, this is certainly worth seeing in IMAX as the huge screen makes a really big difference,of all the recent movies made in 3D,this is by far the best.Make sure you go early to get a good seat as you don't want to be sat too near the front of the theatre too close as you won't be able to appreciate the effects fully!
