According to a post made by Time.com MoviePass is low on funds and now subcribers are no longer having access to the new hollywood blockbusters that they signed up for. What happen? apparently they made a guesstimation that if they as the company take the upfront cost of buying movie tickets at full price then sell for low to the customers for digital access. That eventually the major studios and cinemas would jump in and split the bill.
That never happen. So their entire business model seems to be crumbling. Customers are now experiencing price increases. Theaters like AMC are not having any content shown on the site.
