I don't know, I think there were some unique choices in the direction, all that owed to the clarity of the storytelling. Like Buckingham's political rallying, the ghosts coming to Richard at the last-supper-like table (very eerie), and the whole photo-op when the king is trying to join the two families near the beginning of the play. And I suppose I feel the same way about Kevin spacey's delivery. To me it wasn't filler, but clarity of storytelling. I don't quite understand what you mean when you say the language was reduced to filler, because I was astonished at the power the language rendered while riding forward a series of potentially redundant-feeling events. What's more the production managed to evoke a dream.. Ok this isn't my review, but wanted to put my 2 cents.
Oh, also, I was sitting in 2nd to last row and felt like I was in the Elizabethan theater. In other words, I appreciated what felt to me like HUGE choices on the part of actors/directors. Not to mention, the crowd's unanimous response to shift forward in their seats whenever richard moved downstage was magical and actually rare in our current theater.
