Some skaters manage to appear genuine when they are skating, while others appear fake. And fake is more the norm in ice dance than in other disciplines. Nothing is more fake to me than a smile plastered and frozen on a skater's face continually throughout the program. These are clearly fake smiles and the skater maintains it with a lot of tension. No one can genuinely smile just one smile for several minutes. A smile is basically a expression that moves and is held for a fleeting moment in time - even a 'long' smile. This is most common among female ice dancers. I'm sure that they are told to smile in that way and to reach up way in the stands with it. And it is not as bothersome when there is more distance between skater and audience, more bothersome when watching close to the ice or on TV. One of the things I like about Tessa Virtue is that she has a lot of genuine facial expressions, IMO, anyway.
