I thought this particular feature in the DVD package was valuable because it explains what's going on in the storyline, not how the camera work was done, etc. (That's interesting, too, but totally separate.) It's just basically a synopsis. It's helpful, because upon viewing the film the first time, it seems rushed and confusing, and you care very much about the couple, but you're thinking, "What is going on now?!" It confused and disturbed me, but I couldn't shake it from my mind, and someone suggested that I watch it again. I did, and now I was on track with how the stories unfolded. It hit me like no other love story in this modern age of cinema. And for those of us who love to dissect a motion picture, technologically and otherwise, this particular DVD extra feature made things clearer, so upon subsequent viewings it became more satisfying and fully appreciated. More DVD's should have information like this included in their package.
