Watched DKR last night in IMAX and it was absolutely incredible. The picture quality and the sound and the overall experience was out of this world. Was the first IMAX movie I've seen and will definitely be going back to watch future movies in this format.
Perhaps it's a big call, but IMO The Dark Knight trilogy would have to be up there as one of the best trilogies of all time with the overall quality of the three movies. It's certainly ahead of Star Wars, LOTR, Matrix for me. Apart from The Godfather and maybe the original Star Wars movies I can't think of a trilogy that tops it.
