Almost great

Rating: 9/10 (19 December 2015)

With all that stuff going on about A.I. and its development, Her is a well-written approach to the possible consequences of this technology on a human level.
Acting is good, build-up tension is believable, futuristic world is believable.
The only reason I'm not giving 10 to this movie is because the end should have been Her dying while the company releases Her 2.0 instead of that theatrical vanish.
Would have been more plausible (obsolescence and money driven companies trying to addict you to their product). Maybe the writers didn't want to made this movie as much a critique of capitalism but more about our relationship with AI.
