the problem with all performers and all performances is that it is a two way communication, it is not necessarily the performers fault if he is not appreciated.
From my own experience of being an audience member I know that I could have Appreciated or not appreciated a performance because of my particular mood on a particular day, and could have had a completely different response on another day.
finally we cannot expect everyone to like the same thing, why should we expect lots of people to appreciate Peter, because someone is talented is not a guarantee that they will be liked, meanwhile lots of supremely untalented people who are promoted well are liked by the mass of the people.
