Movie Pass at present only works for "regular" movies and they have been fooling around with their pricing/features lately and along the way losing a ton of money. Movie Pass also sometimes restricts access to block buster movies at the beginning of their run.
AMC has a plan similar to Movie Pass but it only works in AMC theaters but you can using for anything that is being shown. It also gives you a discount on food an drinks at the theater. You are limited to 3 movies a week but for most people it is still a good deal.
