My problem with Movie Pass is that everybody who signs up for the service expects to get more out of the service than what it costs. Assuming that people actually use the service after they pay for it, there is no way Movie Pass can stay in business. In this respect it could resemble a pyramid scheme. Those who paid for a whole year will have to use the service as much as possible before the company folds up, just to get their money's worth.
At least the AMC service couldn't go out of business, because they own the theaters. The worst that could happen is that they stop offering the service.
