Truth be told, when "Star Wars" came out in 1977, I thought it was the coolest thing to ever hit the big screen. OK, my youthful enthusiasm got the better of me. Still, it was a super-fun yarn and a universe better than any other sci-fi plot to get turned into a movie. For what it's worth, the original "Star Wars" was voted the 16th best film ever by readers of IMDB
