An interesting but unconvincing thought experiment

Rating: 6/10 (20 January 2014)

A personal message writer who is struggling to come to terms with his divorce falls in love with his computer's artificial intelligence (AI) operating system. Named Samantha, she is everything that Theodore is looking for - warm, funny and understanding. It was interesting to watch their relationship develop, as well as their attempts to overcome the problem of her not having a body.
I think the movie did the best possible job of portraying such a wacky relationship sympathetically. The acting and music were great, and I really like how the futuristic LA didn't involve people in metal/neon jumpsuits but looks rather retro. But despite these efforts, I still found the movie's premise ridiculous. While the relationship was not without obstacles, I felt that no sane person could become that emotionally involved. How can an OS compare to a living and moving person whom you can cry with and cling to, do crazy things with, and show/receive love in a multitude of little ways?
In short, Her is an interesting thought experiment which tries to show that human-machine/AI relationships might one day be possible. But the answer I draw from watching it is a clear no.
