You're a good father, but sometimes you're a bad dad.
That was one of the most memorable quotes from the movie. There aren't a lot of good movies that are mainly about a dad or a father. It was humorous and funny, but not necessarily hilarious. I was very pleasantly impressed.
I've been thinking a lot lately since I saw the movie about the difference between a "father" and a "dad." I'm not sure what the exact difference is, but I agree with the movie: you should try to be both.
