I mean…if the movie is good you should support it
What is 'it'? The movie is a published work, it can't be financially supported. Who is being supported with the money you pay?
Vote with your wallet.
Unfortunately, consumer boycott (and conversely, support) usually isn't an effective strategy at this scale you're talking about. Unless you and all your friends are voting with a few thousand dollars, it's hardly going to make a dent in the numbers.
