Celtic Woman has been slammed by the Boston Globe in a nasty review that says "If your ideal is a concert that exudes something more than mere spectacle, a show that brims with verve, tension, and a spontaneous, genuine energy that is not choreographed to within an inch of its life, then Celtic Woman falls short."

Is it possible to be too perfect or too polished? Ask Boston Globe music critic Jonathan Perry, who then states clearly that it is, and Celtic Woman are.

"Despite the strong voices and relentlessly feel-good messages of love and togetherness, what was missing from a show calibrated to be perfect was a depth of feeling. Celtic Woman may have been singing from the heart, but one wishes they sang more from their soul and gut.

"Of course, perfection and what constitutes it are in the eye and ear of the beholder. And if one’s idea of musical perfection is a flashy, flawlessly executed spectacle with all the glitz, glamour, and dry ice of a Super Bowl halftime show, then Celtic Woman comes pretty close," the review continues.

"If, on the other hand, your ideal is a concert that exudes something more than mere spectacle, a show that brims with verve, tension, and a spontaneous, genuine energy that is not choreographed to within an inch of its life, then Celtic Woman falls short.

"Celtic Woman delivered exactly what many expected," he wrote "a seamless 95 minutes of high-gloss entertainment that showcased each performer’s sleekly pitch-perfect voice and equal ability to wear an evening gown to stunning effect.

"Although violinist Máiréad Nesbitt sometimes resembled a crazed marionette, her whirling dervish animation lent spark to the hermetically sealed proceedings."
