So first off, to be clear, this is NOT a comedy. There's very little if any humor in it at all. It's not a spoiler to say the Father & Mother of the bride are getting a divorce, as it's literally the first scene of the movie. The father proceeds to spend basically the whole rest of the movie, showing WHY they are getting said divorce. He is, put plainly, an >insert profanity here<.
He spends his screen time antagonizing his whole family. He talks down to them, he talks over them, he ignores everything they say and everything they want. He forces himself to be the center of attention, and by his own statement (multiple times) says that because he has money he gets to make all decisions. This ignores the fact that the Bride & Groom expressly state they don't even want his money, but he forces the issue. This is interspersed with solo scenes of him moping around, sad faced, lamenting the current state of his life (which he's brought on himself by his own horribleness). It's clear the writers try to include moments where you're supposed to feel some sympathy for him, but this is completely overshadowed by the fact that he is written as an absolutely unlikeable >repeat profanity here< who doesn't actually earn any sympathy.
When you've made it through 90 minutes of a 2 hour movie, and you realize that you simply don't care about anything at all that is happening in the slightest, that's a giant red flag. When you dislike a character enough that you don't care about the writers sad attempt at a redemption arc, another big red flag. This movie was a great example of both.
