I had the same experience, too. For years I saw 2001 on TV, VHS tape, LD and DVD. Then I had one chance in a lifetime to see 2001 in the year 2001. It was on a restored old theater, complete with pre-show music, and special lights that slowly went out one by one until the movie started. For the first time, I was not bored of the Dawn of Man sequence. My attention was held, and I think the placement of the intermission was also important, too. Hope I get the chance to do that again.
