The MoviePass customers that most used the service (aka >3 movies a month) were also the ones least likely to buy concessions. Thus, theaters had no incentive to give MoviePass a share of their gross (meaning total) concessions revenue in lieu for increased ticket revenue.
However, if my marginal cost to see the movie is $0, it turns out I was willing to spend $5 or so every so often to get something to munch on during the movie.
While I haven't spent a huge amount on concessions, I've probably spent more on concessions in the 6 months I've had moviepass than in the combined 30+ years preceding it.
There's no need for the middle man.

I would disagree that movie theaters are hardly a monopoly. You usually only have one in a given geographical area. In a major metro you may have more options within a short distance but even then they are usually not walking distance from one another. And even if there are multiple options in same locale they may be same company and still a local monopoly. For example in Chicago, there are 4 movie theaters in downtown area, 3 of them AMC.
That's why I was careful to say "economic profit". On the books numbers are all well and good. But the only indicator I'll take as a sure sign that an industry is profitable in the economic sense is if the number of firms in the market is climbing (i.e. new people are scrambling to get in on whatever benefits they perceive there are to being on the supply side of the market). And movie theaters seem to be more or less in an equilibrium to me.
