Don't expect anything too deep when watching this movie. It literally feels like cracking open a beer and letting oneself unwind/unravel.
There's no captivating plot, but as an older woman (I'm going on 45), it was fun to see gorgeous French women in the same age group as I am having non-commital relationships and enjoying themselves. They do touch (very briefly) on how society looks at relationships strangely - ok for older men to be with younger females, but not accepting of older women with younger males.
It was cute and funny. Don't expect everlasting love. That was never the point of the plot or movie. Go in with a carefree, open-minded mentality and you'll enjoy the movie better that way.
