It's truly one of the greatest films ever made, a crowning achievement that feels positively impossible to have been made at all. Thank god this came out in the height of the DVD era and we got deep behind-the-scenes and commentary tracks for these films. It would be such a crime to only get the overly-produced, hide-the-real-work BTS stuff we get today. I can't imagine how many people people got into movie making and special effects based on these features.
