I've heard from several people that they have a hard time getting past the premise of Her. That's fair enough; it's about a dude who develops romantic feelings for his phone. If that's all you have to go on, it's a tough concept to buy into. Even if you accept the main character's feelings, how are you supposed to relate to them? Fortunately for me, I had several other ways into the film.
First is the cast. I love every one of the people mentioned on that poster. Joaquin Phoenix is one of the finest actors working today, as is Amy Adams. Rooney Mara and Olivia Wilde are also very talented and I have good feelings about them from Side Effects and House respectively. And even though Scarlett Johansson's face never appears in the movie, she's also a great actor and I love her voice. Then there's Spike Jonze, an ambitious filmmaker with interesting things to say and powerful ways to say them. And finally, there was hardly a Top 10 list for 2013 that didn't include Her on it. I knew it would be about much more than a creepy relationship and I was right.
Her does have some things to say about the relationship between people and our technology. That's actually the least insightful commentary it offers though. It's not profound to suggest that we love our phones and computers, but Her goes much deeper than that. It's about relationships in general. What do we want from them? How much work are we willing to put in?
