Loved Her - What's your opinion?

Just watched this move and the only negative emotion that I am feeling is regret, for not seeing it when it came out! Damn, this movie was great! Superb acting, amazing universe and plot. Samantha's character was developed so well that over time, you yourself almost fall in love with her. I realized that when I kept catching myself mildly panicking at the thought of her simply disappearing, since she is an AI and not a human being. Also really enjoyed the premise and the subtle ways that Her hinted at humanity's technological advancement.

I have been a long time lurker here but this one made me want to share my feelings.

Would love to hear your guys' opinions about Her. Let's have a discussion!
