I have them all and Tangerine Dream is what gets watched the most. IMO, it was the end of an era... not good or bad, but it felt like the last hooray for quite a few iconic skiers.
A must-have is the Big One which highlights every Jackson segment from the first 10 years. Further just for the Nobis segment. The Continuum, not because it was the first one but when Bob Marley hits in the beginning, always get chills down my spine. Loved Lost and Found as well (Marc Andre segment, and Sage skiing with Candide). Don't really care for any of the latest ones (UTI, Re:Session, Light the Wick, OFTR). Seems like the art of filming is lost with these. Yeah, it's ski porn, but the older movies had way more soul in them.
