Smart & funny movie.
At first I thought the dramatic thing that Steve Carrell does at the beginning of the movie was completely unrealistic but after watching the movie & hearing how he feels I can understand how it is possible. It seems like something in his position would do.
There is a lot of good advice in the movie, some of it realistic & some of it so idealistic it would only apply in a movie. The movie knows this as one character says that she "is not pg-13" that is rated R. & she describes a common movie trope. They even mention other movies like Dirty Dancing & the original Karate Kid so it helps to have seen those other movies.
It was a really well-written fantasy because people do not really talk like that & those kinds of things don't really happen but I think the movie can inspire one to try to be like the characters in the movie. Which isn't such a bad thing.
