“Over the top” doesn’t begin to cover Marc G. Dalio’s performance as Belle’s oafish and ultimately rejected suitor, Gaston, in Beauty and the Beast. He came across like a huge, muscled and inexplicably animated cardboard cutout, prancing and preening, utterly in love with himself, his grin revealing teeth as large and white as pillowcases. Dalio has a big supple voice and oodles of stage presence, and his song and dance with his mates in the tavern brought down the house.
