This is going to be a movie with Jason Bateman, so I gave this another try. I started reading this when it came out, but I was turned off by the vulgarity in one of the early scenes. The turn-off wasn't that Judd (main character) walked in on his wife having sex with his boss, it was that he then took a cake (with lit candles) and pushed it on the boss's behind...That's where it lost me. But now, picturing and hearing Jason Bateman's voice helped make this more enjoyable. I was able to spend time with Judd and his dysfunctional family, wondering how they'll do the movie. Hopefully they'll improve it. The humor in the book relies too much on people being assholes to each other, but the book itself has a snappy pace and balances the dysfunction with Judd's inner turmoil dealing with his wife's abandonment and his dad's death. 
 Update about movie: 
 The movie actually improved on the book, the screenplay was less vulgar. When Judd walks in on his wife, he's crushed, and just holds the cake. The movie bestowed more depth to the story, more sentimentality. And it had some of my favorite actors: Jason Bateman, Tina Fey and Adam Driver.
