So THIS is the downfall of skiing?
Lay off. Ok, I'm going to take it upon myself to break a few things to you:
First, how you get "style" is up to you. Not up to me, or anyone else. It's up to you. If something strikes your fancy and you do it well, that's probably your style. Emulation may be the biggest form of flattery, but emulation kills originality.
Second, have you seen a ski movie from before 2004? Go watch "Ski Movie" by MSP or "The Game" by PBP. TONS of flailing. Guess what, everyone starts somewhere.
Lastly, no one likes negativity. It won't get you respect, and it definitely won't get you a girl. If you think his skiing is such an abomination, why don't you teach him? Man up and do something about it if you're so concerned about the "downfall of skiing".
I applaud the guy in the video, because he's probably having fun and he's got some talent.
