anchor: The good news is that when a movie is good , pretty much everyone can afford to see it, which isn't true, say, of a concert reuniting Bruce Springsteen with the E Street Band (though in the latter case the price differential is not the Boss's fault, but rather the fault of ticket scalpers and brokers).
positive: Because movies have a wide distribution, cinema ticket prices are affordable.
negative: Even if a movie is good, only very few people have enough money to see it.
