If someone likes movies as recreation, even if they would prefer something different than the action blockbusters, their choices are "don't enjoy yourself to send a message to the studios" or "watch a movie you might enjoy less than something from another genre"... most people who enjoy watching movies are probably gonna chose the route that still lets them enjoy watching a movie.
The incentives don't line up. Its like buying McDonalds at an isolated highway rest stop - I don't particularly love McDonalds, but if my choices are a hot meal or whatever I can get from a vending machine or pack with me, I'll take the hot meal every time. Its not an enthusiastic endorsement of globalized fast food chains despite my paying for it.
