Not necessarily. Movie tickets in San Francisco run about $14-18. I pay $9.95 for MoviePass, so even if I see a movie every 6-7 weeks, I still come out ahead.
You will come out ahead versus just buying tickets directly, but you will come out BEHIND using this new Cinemark service. The question was how can Cinemark compete with MoviePass, not about MoviePass versus individual seat purchases.
Assuming you have equivalent quality cinemark theaters everywhere you have other theaters. There is one cinemark theatre in SF and it doesn’t show all major films. There are some 8 theaters in SF you can use with movie pass.
