I've seen 2 movies in IMAX, Matrix Revolutions and Batman Begins. Matrix was a good experience, but Batman was a bit of a headache, mainly because of the way that the fight scenes were shot, but both were shown LETTERBOXED on a big screen. I do love widescreen, but to see two black bars twice as big as me for a ticket I paid extra for, kinda reduces the experience for me. Expecially after seeing IMAX trailers before the movie, which feel overwhelming. I'm just saying that more filmmakers should compose for IMAX as well as the regular cineplex. I've seen movies like Cleopatra, that were clearly composed for 70mm, which look like actors running about like tiny gnats compared to today's movies.
