Daddy's Home follows the story of Brad (Will Ferrell), a man who so desperately wants to be a father. One day, Brad meets the love of his life, Sara (Linda Cardellini), who just so happens to be a mother of two. Now that Brad and Sara are married, Brad becomes their stepfather, and things couldn't be going worse. Or so he thought. Soon, their biological father, Dusty (Mark Wahlberg), comes to town, and he's everything they wanted out of a father and more. The relationship Brad was trying to create is lost, and he's not happy about this. So, they have what is essentially a dad-off, trying to compete to become the favourite dad. With a premise as wacky as this and a cast as talented as they are, this film shouldn't have been as bad as it was.
It's a film that tries to give messages about family, but it's never really sure what these messages are. Some scenes are trying to teach kids an important life lesson, yet the next scene completely contradicts this message and says it's okay to bully. It's an uneven and unfunny movie that tries to be so many different things at once, but isn't even capable of creating a plot that works. The dad vs. step dad premise that we saw in the trailer doesn't even really start until the third act. Up until that point, the film is just the two leads bantering back and forth and it's far from entertaining.
To sum up, Daddy's Home is a film that really should've been funny, but so isn't. It's a boring and uneven movie that's never sure what its target audience is or what message they're trying to teach them. It's all over the place.
