I'm not a filmer, much less a serious one, but I see what you're pointing out. But I didn't notice it until you brought it up. I think certain tricks/lines look better zoomed on the bike and some better with a wider perspective. Sometimes I'll come across a techy clip in an edit where I wish I could get a better view of the bike and everything that's going on in that moment. And vice versa.
In short, there's no proper way of doing anything when it comes to art. Filming an edit is an art form. A filmer is an artist; he can display his work in the way that best captures what he sees in his mind. Altogether, the style of riding, the music flow, clip length, angles... imo it fit pretty well in Begin's edit. Minor shit like cut off head/shoulder/ground etc doesn't really reduce from the total package.
You can't satisfy everyone. Cool that you're passionate enough to critique his work though. Keep doing what you love.
