There are big laughs left and right, non stop!
It was well written by Ferrell and Adam McKay.
You might think they’re creepy and just too pathetic, but it’s a given that’s what they were going for.
You’ll be close to crying 
when it’s all said and done feeling as though you laughed through the whole thing.
This movie was certainly a great way for Will Ferrell to step back from his non-stop drunk and over the top characters, and to finally play opposite someone as funny as he is.
When Robert and Nancy marry and move in together, Brennan and Dale are forced to live with each other as step brothers.
As their narcissism and downright aggressive laziness threaten to tear the family apart, these two middle-aged, immature, overgrown boys will orchestrate an insane, elaborate plan to bring their parents back together.

Goofs
- Continuity: When Brennan is singing at the Wine Mixer, he holds a note that shatters the glass helicopter sculpture. A few moments later, when the scene shows his mom and step dad smiling at the end of the song, the sculpture is intact in the background.
- Errors made by characters (possibly deliberate errors by the filmmakers): At the Catalina Wine Mixer, the cover band “Uptown Girl” refuses to play “We Didn’t Start the Fire” because they only perform Billy Joel songs from the 80s. However, “We Didn’t Start the Fire” was released in 1989.
- Continuity: During the first dinner scene the ketchup bottle changes from being on top to being on bottom when they change angles.
- Revealing mistakes: During the school yard fight at the end of the movie it is quite obvious that the “students” are really much older stunt people.
- Factual errors: At the beginning of the film it is revealed that Brennan is 39 years of age. Later, during a bedroom scene with Dale and Nancy, it’s revealed that when Brennan was 17 his brother, Derek, won a talent show by lip-synching, “Ice Ice Baby.” Based on Brennan’s current age that would date the talent show as taking place in 1986; “Ice Ice Baby” wasn’t released till 1990.
- Continuity: Robert is eating a tree-shaped cookie while he drinks during the Christmas scene; when he gets up to leave, the cookie is whole again.
- Audio/visual unsynchronized: The drums heard at several points during Brennan’s song at the Catalina Wine Festival quite clearly don’t match up with what Dale is playing.
- Factual errors: In the Wine Mixer scene when Dale is first playing drum rolls, it sounds like he is playing them with drum sticks, but it is showed he is playing them with yarn mallets. In real life performing a drum roll with mallets would not sound the same as performing it with drum sticks, and would be a lot more difficult.
- Crew or equipment visible: After the drive home following the failed Prestige Worldwide presentation, the boys burst into the house. To the right of the main entry door there is a mirror, and a crew member in black clothing can be seen trying to stay out of the shot.
- Errors made by characters (possibly deliberate errors by the filmmakers): In the tree house scene, Derek tells Brennan and Dale that he “hasn’t had a carb since 2004,” however in the dinner scene that preceded, he is shown drinking a Heineken (beers are mostly carbohydrates).
- Continuity: When Brennan is showing Dale how good a singer he is, the samurai sword is on the floor between them. When Brennan stops singing and stands up, the camera angle changes and when it goes back to Dale the sword is gone.
- Crew or equipment visible: When the two brothers are on the boat, we can clearly see the reflection of the camera in the polished metal arm under the wheel of the boat.
