MoviePass is a service you can subscribe to, so in essence, yes. It's a service that you can use to book tickets. They pay for the tickets each time, so you as the subscriber only pay the monthly fee to them.

I pay $9.95 per month to MoviePass and I can go see one movie per day at no additional cost.

Right now, they are only a booking service. They don't have any sort of streaming capabilities. They are more interested in using the viewing habits of users from an advertising point of view.

I hope that helped clear things up. Let me know if it didn't.
