Pretty much exactly what I was going to say.

I'm fond of melisma, and of Classical ornamentation as well - vocal backflips are fun, after all, and when I'm in decent condition I can do them fairly well. But a bloody "pop diva" sounding like she was pushed down a flight of stairs while singing a ballad just makes me want to push her down those stairs for real, preferably gagged.

To paraphrase Noel Coward, ornamentation ought to be a glorious treat, like caviar; one shouldn't spread it about like marmalade.
