I was the same age as Drew Barrymore's character. I wasn't scared at the ET being sick scenes, but when Drew's character screamed bloody murder at an earlier point in the movie, so did I.
Saw it at a drive-in, in my mom's station wagon. Ah, the memories.
Okay, actually, now I just remembered a funny story about the first time my cousins saw the movie. They were 12 and 10, and had both come into town for my wedding. The day afterwards we put the movie on to keep them busy while all the adults did something else. I wandered into the room and said, "Wow, hard to believe that was Drew Barrymore." The twelve-year old freaked out. "That's Drew Barrymore?!?" I think I blew his world view about pre-teen sex symbols.
