IMAX DMR is not True IMAX. Bring on True IMAX movies shot with True IMAX Camera like TDKR. I think only Christopher Nolan shoots with True IMAX camera. Most of it what they label as IMAX movies are shot with Arri 4K or RED Epic 4K/5K (Peter Jackson used this for his HOBBITS movies, these are the closest to IMAX superb definition).
My biggest regret is not to watch TDKR on IMAX for a hundred times more. All IMAX movies I saw has been a series of disappointments (PACRIM, GRAVITY, WRATH OF TITANS). HOBBIT2 & OBLIVION, PROMETHEUS are the only movies that are not shot with IMAX cameras but achieve IMAX-like definition & experience. PROMETHEUS, directed by Ridley Scott, is the best looking scifi since.....ever. Too bad the writing is super bad. TF3 DARK OF THE MOON is a superbly lensed & processed movie. Worth to see it on IMAX. Just need to tell the filmmakers not to go crazy with the super-tight framing & dizzying MTV fast cuts.
