Just to throw in a perspective outside the duet (or is it duel?) we have going .... yeah, it makes zero sense to watch the prequels first because they presuppose you already know stuff learned in Episode "Four" (e.g., what's The Force?) and - of course - they ruin the great surprise of Episode Five (and yeah, the S.E.'s ruin the great reveal of Episode Six).

So, for those and a zillion other reasons, NEVER exhibit the movies in numerical order to a Star Wars virgin. (Laying aside the fact that making someone wade through 3 bad movies to get to the first good one is a very stupid idea).
