What to do when one gets old? The question you might have to ask yourself one day (and we all hope we'll have that problem ... well we may wish to stay forever young, but that seems to be out of the realm of reality) ... and one that is the essence of this movie.
There is voice over to introduce us to this concept and to the 3 main characters. All of whom get a job - like a nanny ... but as the english title suggests "granny nanny". Now one of the characters is male so technically it isn't just grannies ... on the other hand, some might call him feminine so there is that too.
But all that aside, the movie is quite fun and has rich characters with their own issues and while they are old, they still can learn new tricks (yes the saying - I'm aware of it, so I reckon pun intended) ... Interestingly and charming, for those who care and don't mind seeing old people on their screen struggling with a newer generation, they almost have nothing in common with ... or do they?
