I would say this one of my best movie. It is emotional, sad and funny, but funny comes out of utter boredom so it is mix of sadness and hopelessness.
The girl and guy both lost into their loneliness. The movie makes sense how it is painful to be lonely and then how the talks with stranger can be so opening, the talks with the known people (in this case his wife) means nothing, bored and dry.
The movie makes to us how we are all lonely until we open ourselves to stranger and starts relating with someone who is completely unknown, then it become kind of healing. Many times you will see how Bill Murray express all his frustration without saying words at all !!!! . he is so much into the character. The best acting!!! But Scarlett Johansson has done the superb acting.
The movie ends when Bob runs after Charlotte and gives her hug and says something in her ear, we don?t know what it was but it seems he thanked her. The end is kind of healing process !!! I loved it !!!
