I am going to attempt to respond to this...
I agree with OP. But not in the entirely in the same light. I think it has a lot to do with perspective when filming these shots. It is sort of hard to really capture the extreme part of the equation when filming big lines, you have to really understand what the skier is doing to be like "oh shit, that was intense". TGR last year did on of the most cinematic jobs of showing what big mountain skiing is like, but at great expense. Way of life was a great film, and probably has some of the best shots of big mountain lines, but thats because the used non traditional camera angles.
usually there are only 2 (/2.5) angles used. Firstly, POV, which is intense, but it sort of lacks the ability to see the whole face of where the skier is. The other angle is from in the snow field below the line with a tele lens zoomed in on the skier, but this lacks the idea of the angle at which the skier is going down. But what do you get is the ability to follow the skier all the way down the line. the .5 is a similar shot, but just off to the side more then at the bottom of the run out. and just to create even these shots a lot of time and money is spent. TGR did a lot of heli fly bys and filming from a hovering heli which was unique and more captivating.
also, the music almost always sucks in these big mnt edit, always the same. I will agree there.
I personally enjoy big jump sessions (MSP at whistler, etc) because its slightly more relatable (though i will never throw triples or even doubles, for that matter, on a 70+ foot jump) in ski films. This is over all more cinematically gratifying to see.
I'm sure 75% of this is wrong, so feel free to flame me. but this is what I'm writing while i should be paying attention to my audio engineering class haha
