The Birdcage - Half a plot - Screenwriter's nightmare

If you haven't seen this Hollywood remake-movie from 1996, it's about a college kid whose parents are two gay men who run a cabaret club in South Beach, Miami.  The college kid wants to marry a girl whose father is a U.S. Senator who chairs the committee for Moral fiber.

The movie has funny parts and it did gross $200 Million at the box office.

BUT in terms of storytelling, it delivers half a movie.

When it is revealed that the college kid's parents are two gay men - which feels like a MIDPOINT - the movie quickly jumps to the two college kids getting married and the credits rolling.

The Senator is up for re-election and we lose the opportunity to see if he loses his job.

No single character has to sacrifice anything.  No character learns anything.  There is no point to this story.
