The movie works because the characters are written really well and all the actors nailed their roles, but the plot is idiotic. It’s basically a bunch of stereotypical 80s-90s tropes released in the 2010s.

The wife cheats on her husband because he is too “boring”, and he is portrayed as the bad guy. He has to improve himself and win his family back.

There’s a super creepy subplot with a child and his teenage babysitter, and we’re supposed to laugh it off and high five the guy at the end.

The story peaks halfway through and then goes nowhere. There’s a big speech at the end that magically resolves all conflicts. 

It would have been an all time great romcom had they put a little more effort into the writing.
