When E.T. came out in 1982, I wanted to see it. Every kid I knew wanted to see it. I lived in a rural area growing up, and people from miles around came to the one movie theater in the area. In fact, the original showing was full by the time we arrived, but they were doing a later one due to the crowds. We made the later showing, and sat on the floor. Since my sister and I were young, we didn't care. When you get older sitting on the floor is a bigger problem.
I only saw the movie that one time, and never again. I enjoyed it, but I watched it as a kid. I'm sure most of the references were over my head, and I missed subtleties that I would have picked up as an adult (for example, how did the mom manage to miss an alien in the house?). My sister asked a lot of questions and I tried to answer them as best I could. I do remember the end, and I cried a lot, it was sad when E.T. left.
Like most things from my childhood, I'm afraid of revisiting it. The ending won't be as sad, and I won't be sitting on the floor of a crowded movie theater answering questions. I liked the movie as a kid, I can't see liking it as much as an adult. I enjoy the memory the way it is.
