Compassionate

"Her" is clearly a drama, but comes up with unexpected comic moments again and again.
The film shows very clearly, without drifting too much in the direction of science fiction, where could lead the development of today's technology (smartphones) and the Internet.

The protagonist is first course alone and depressed. Through a spontaneous decision enters a "woman" in his life that brings to speak using their voices alone and your way of saying in his life (well presented in German by Luise Helm).

However, this woman's not real but produced by the artificial intelligence in a computer OS.
Just get through the continuous and autonomous development of the OS, this developed its own personality, which inevitably leads in this scenario to a relationship between him and her.
The way of looking at the artificial intelligence is very philosophical and shows what problems could bring a fact independently developing artificial intelligence with them - one's consciousness.

Although the main character performs his most personal conversations with his OS, he does not lose touch with the real world and keeps his real friendships upright.

Through small overlays the point of view of the OS will be shown from time to time, which are generated by the mobile terminal.

--- (Maybe spoilers) ---

Very impressively comes across the despair caused by the impossibility of a real relationship between the two.

The end of something suddenly comes but also predictable.

(SPOILER ->
First, the invented during the film end is initiated by the OS crashes due to a technical defect and whose personality has been lost. Here it comes again, although to a turn, however, a separation of the two is inevitable. Whether the end now is logical or not is irrelevant.
It is virtually the only possible end for this tragic yet sensitive love story.
That what he is at the end of it (besides the memories) is compiled by the OS collection of letters he has indeed written on behalf of strangers, can be seen here, however, as the only possible physiological link between the two.)

The main role is busy ideal with Joaquin Phoenix.

PS .: The elevators are amazing ;-)
