Not sure why the low scores because this is a delightful and funny movie. Maybe it is because it is a cast mostly of middle-aged and elderly. Or maybe it is because western social attitudes about older people not being as interesting as those under 30. Or people are made uncomfortable by the thought of old people "doing it". "Old" people aren't supposed to be silly, irreverent, sex obsessed or pranksters? Well, from the elderly I know in real life, they definitely can be. It's really only illness and infirmity that puts a stop to it, if you were silly, irreverent, sex obsessed or a prankster when you were younger. Perhaps not even then. (I visit and occasionally have lunch out with a lady in her 70's who likes to scope out and then point out good looking young men to me. Not because she is trying to fix me up, but according to her, because she likes looking at good looking men!)
I don't think this would have been funny if this was about teenagers or twenty-somethings because it has been done to death. Using the older generation gives a tired old genre, a fresh new twist. It is filmed as if it were a documentary, and the unseen camera holder is mentioned a couple of times. But, unlike another review, I did not care for the beginning and almost stopped watching because of that Tyler Perry "filming a play for a movie" feel. Luckily, that changed after just a couple of minutes.
There are also some nice cameos, including a hilarious Christopher Walken impression by Kevin Pollak. While it isn't an Oscar contender, it is definitely an entertaining film worth the watch.
And I want that red "bikini".
