Grew on me over time.
I was into robot sci-fi as a kid, but I wasn't ready for AI when I first watched it. I felt disappointed and just thought it was an ok movie. Now that I've gotten older I genuinely love it. It has grown on me for years. Just the thought of David sitting there for 2,000 years gives me goosebumps, especially the scene where the frozen remains of the World Trade Center are shown. It adds even more emotional power to the scene and the ending really gets me every time. It has turned into one of my favorite films now. It's one of those special gifts that took me years to appreciate. I love films like that.
