Overrated? No way.
It's overused, though, in the eyes of some (mine).
To each his own.
Like a guitarist doing a solo every damned song? How did we ever survive the dark ages without guitar hero's? lol
I think if the music doesn't call for the MWAH sound, don't put it in. You can play a fretless to minimize mwah, not real difficult. Some folks just have to learn to hold back a little on the fretless. You don't have to change to a fretted, you just have to change your attack and tone a little. It's all in the hands, and the smarts to know when and how to use them.
