I've watched one many, many, many times over the a period of at least 20 years, being fascinated by the mystic and legends surrounding not only the movie, but the leading star, even going so far as to watch a very entertaining fictional movie made several years ago about the shoot.
The other I have yet to see and have no desire to see.
And to answer the question I am sure you have all been asking yourself: Yes, I do have a time machine and have been using it to watch Twilight over and over, 20 years' worth.
