Why do cinemas not like it? They get paid for each ticket and people go more frequently.
The AMC average ticket price for watching a movie at AMC Theatres in the most recent financial quarter was $9.33. From what we can tell, by definition and absent some other form of other compensation, MoviePass will be losing money on every subscriber seeing two movies or more in a month. [...] In AMC’s view, that price level is unsustainable and only sets up consumers for ultimate disappointment down the road if or when the product can no longer be fulfilled. AMC also believes that promising essentially unlimited first-run movie content at a price below $10 per month over time will not provide sufficient revenue to operate quality theatres nor will it produce enough income to provide film makers with sufficient incentive to make great new movies. Therefore, AMC will not be able to offer discounts to MoviePass in the future, which seems to be among their aims. While AMC is not opposed to subscription programs generally, the one envisioned by MoviePass is not one AMC can embrace.
MoviePass has proven theaters are interesting to more people than I'd have thought in a world of 70"+ TVs and 4K streaming. A smarter Pass could experiment with non-peak times, second release movies, and concessions.
Average ticket price really isn't the best metric with the fixed costs of a theater.
If Movie Pass fails it still helps set an unrealistic price for the cinemas who won't be able to match it. It may drive even more people away from cinemas who no longer wish to pay full price.
As a MoviePass customer I buy more concessions since my budget isn't blown on the ticket.
