GREAT review, ferris! One of your best, which is only appropriate. If I didn't already love this movie (and have seen all the versions at least once), I would be rushing out to watch it right now!
One thing I must take issue with you, though-- 1980, we were CERTAINLY watching movies more than once. I watched Star Wars at least 12 times in the theatre in 77-78, and in 1980, I saw Empire a few times and Airplane! and Any Which Way But Loose at least twice each. And how many times did you watch Raiders, which came out the next year?
