I don't know -- I watch him play and I'm pretty impressed. The ending of HR6 isn't exactly a nocturn - the emotional part, and my favorite part, of this piece is the slow section preceding it. But I see this video starts after that section, and I haven't yet searched for the whole thing.
I've read impassioned writings about how Hamelin is sterile, Lang Lang is vulgar, Kissin has no musicality, Cziffra was a circus act, Horowitz was overrated, and so on. Seems like every time someone pulls off an amazing performance, a lesser performer is there to point out how cold and emotionless he is. This is the same thing that Liszt faced in his day, and these same people 150 years ago would be slamming Liszt for his superficiality and showiness. I think that anyone who has a critique for this guy's HR6 should be able to sit down at the keys and say, "THIS is how it should be done."
