Madonna knows how to make a video.  Her collaborations and performances in each little gem has been one of the strongest aspects of her amazing career.  Unfortunately, she doesn't know how to make a DVD.  For a woman who's made a career out of being unpredictable and pioneering, her efforts in showcasing her work in the DVD format have been surprsiginly ho-hum.  Where are the extras?  Where's a behind the scenes look at the making of any of these groundbreaking clips?  And why are clips missing?  Why not include "Deeper and Deeper", "This Used To be My Playground" and "You'll See"?  And where is "I Want You"  and "I'll Remember"?  I had read that "Erotica" was left off the collection to avoid a Parental Advisory sticker plastered across the packaging.  I hope this isn't true.  Could the woman who released the "Sex" book really be all that concerned about such a warning?  I'm sure there are countless reasons for such glaring omissions.  It is said that Madonna hand-picked the videos that she's most proud of for this release.  And, without a doubt, they are all great videos.  But with expectations so high for both Madonna and the DVD format, why not give a little extra?  I've given this collection five stars for the content alone...but as far as DVDs go, this one not only could be better but should be better.
