About the ending (spoilers)
This film was awesome, which is somewhat strange to say about a film that is based primarily on dialogue that occurs mostly between no more than 2 people at a time. The "awesome factor" comes from the emotional depth coming from each of the main characters, which culminates to a climactic yet subtle ending.
That being said, I would like to get other peoples' reactions on the ending, namely the dialogue between the husband and wife after he abandon's Chloe. It is very tense followed by tears from the wife, which brings me to ask, did the wife cry because she knew about the affair, or was she having an affair herself?Or other theories?
