I'm going to upset my boyfriend with the movie selection I made
How do you think he'll react to the movies you picked?
I  expect him to be mad at me, but I'll apologize later for this
I can see why you would want to be able to select your desired movie.   You should also keep your boyfriend's wishes in mind so that you do not cause tension over a small issue.
I know, but he can't make all his dreams come true, so I will get what I want and enjoy it.
If he can't make his dreams come true maybe you can help him out? I'm sure he'd appreciate you being understanding of his struggles.
