It really isn't anything to do with good and bad players - it is the limitations of the instrument itself.
As well as it might be played, its very nature makes it intrusive in a session of good musicians and it turns an average session into muzak.
It has been around for a long time, yet it wasn't absorbed into the music in Ireland until Sean O'Riarda (a classical musician) deliberately introduced it. It was an instrument played at rituals such as 'The Wran'; the old musicians were clear on this when they were asked about it. Ennis wasn't the only one to despise it, most musicians I've talked to regard it as irriating as spoons or coins banged on tables or glasses.
See the long article on it in Fintan Vallely's 'Companion to Irish Music' (somewhere on another bodhran thread).
