When I saw the summary of the movie with a bright, strong image of the characters, I thought it would be quite exciting to see a movie about a (kind of) love triangle of elder people.
I mean, feelings constituted on pity, gratitude, humanity or any other cliché about age really bored... Thus, the possibility of seeing a story about elder people which doesn't care about age itself was exciting.
Additionally the strong sex images in the movie made me think the director will open up some provocative conflicts...
However, the script was so conventional and straight... Maybe the word shallow can fit here, I don't know... The problem for me was, without the detail of the characters age, there's nothing special in the movie. On the other hand, the concept of age should be totally discarded (so we should be looking for something else?) or discussed... Neither of them was there, so there was just a lack I guess...
