I think the realistic, yet funny, mother/child relationship has a lot to do with why this is such a pleasant movie to watch. Someone commented that this movie will probably not be enjoyable to those under 40 years of age, but I would have to disagree with that. I'm 19 now and was even younger when I first saw this movie, yet I still think it's one of the most enjoyable movies I've seen.
Everyone has different taste when it comes to movies, but I think everyone should watch this movie at least once. It will bring back memories, and I'm sure you will enjoy it regardless of your age.
