I agree with 
Carorëiel and was actually looking up this quote and noticed that it was just posted.  
Glirdan, I believe what the point Saucey was making is that Legolas was walking on the snow with little imprint and that's not technically possibly yet in a fantasy world it is.  
Though more on topic I don't see any major problem with this particular stunt.  There needs to be some amazing things happening here.  It wouldn't be, cinematically speaking, as interesting if Leggy merely shot him from a distance and the battle was over.  While this is a bit over the top that is all it is.  The other stunts are more exorbitant in their realism and more of a gratuitous insert to make the women swoon (coughbethberrycough) 
 
  
 , especially the shield surfing.
