An outstanding quartet of local actors drove beyond the shortcomings of I Love You, You’re Perfect, Now Change to offer up an insightful, sometimes hilarious look at America’s love-hate relationship with dating games. Whether they were dovetailing in four-part harmony, pairing off in warring/cooing duets or going it alone during a few gratifying solos, Mark Devine, Jordan Leigh Gurner, Elizabeth Rose and Gina Schuh-Turner exuded a winning combination of artistry, timing and humanity. Best of all, they ushered in a welcome change in area casting trends, proving that local talent can bring as much — if not more — to the Denver Center’s stages than most any assemblage of ringers.
