Looking at their plans (https://www.sinemia.com/new-plans/) it's capped at 2 or 3 movies a day, available at any theater and in any format. You can also apparently buy advance tickets, which is a huge limitation for MoviePass.
Their business model seems more sustainable than MoviePass, too. Well, at least when it's not heavily reduced due to the Oscar promo.
The main advantage is reserving tickets via fandango or any other website that sells the tickets. Personally we didn't watch more than 2 movies a month in theaters, so this works great for us.
