Teddybear Crisis is the most complete ski video of all time for me.
It has a full range of types of skiing, a lot of the best riders of its time, iconic moments, mostly bulletproof soundtrack, lived up to its trailer which was dope, well shot and edited, actually feels like a piece of art beyond simply a highlight reel. Hard to ask for more from a ski film. Obviously camera quality and amplitude of tricks have changed. There are still plenty of hits that translate to today in terms of the style and level of send, and some slams that still raise your eyebrows. If you haven't seen it since it's 18 ish years old now I'd highly recommend:
