'Her' has an interesting concept on its side, and is helped by some good performances. However, the movie suffers with some pacing issues and, for reasons hard to pinpoint, I didn't feel as invested as I should've been. Many are loving it, so if the concept sounds interesting to you make sure you check it out for yourself.
Every plot point that does not revolve around how amazing the OSes supposedly are is short and underdeveloped, and as such, every time we're supposed to identify with a main character having difficulties with their interpersonal relationships and seeking solace in technology, it just feels tired and distancing.
Establishing at the beginning of the movie that the love interest is a computer automatically makes everything Samantha says feel incredibly fake, no matter how much Scarlett Johansson throws herself into her lines. We already know everything she's saying is based on her programming, and as such, we're subjected to a depressing two hours of a lonely man falling completely for a clever trick that basically equates to when we ask Siri to tell us a joke.
The aesthetic of the movie is nice (although the decision to have so many of the main characters sporting cringey, creepy uncle moustaches was unfortunate) and the nice, colorful city shots are enjoyable for the first ten seconds, but then start to drag as the protagonist stares dramatically into the distance with his brows furrowed as he listens to his earbud.
The person I saw was with was very moved, but I felt absolutely nothing watching this. It just made me wrinkle my nose and roll my eyes a few times. The only way I think this movie works is if you can see Samantha as a metaphor for a long-distance relationship, in which case the story is touching, but not particularly inspired. However, forcing the audience to stoop down and play along with your completely irrational love story of a gasping, moody computer making the protagonist depressed for two excruciating hours does not work. I could see this working a little better if they had made Samantha slightly more robotic, predictable, and with an even slightly even voice, but alas, they went for the melodrama. I regret watching this. Read a synopsis and don't waste your time.
