I caught this via the TodayTix lottery Wednesday afternoon. Initially I lost, but got a text asking for a reply if I was still interested and then I had 10 minutes to complete the purchase once they tagged me a winner. I was row E, house right. I guess technically it was obstructed but didn't really miss anything that I can recall.
As far as the earlier question about whether he wears a prosthetic nose, he indeed does not but he does make a comment about it early on. I enjoyed Dinklage's performance, but found the show just OK - it was good enough I didn't regret going, especially for $35.
