Mr. Maroulis meets the throat-thrashing challenges of Mr. Wildhorn's score with aplomb, his high-reaching pop tenor evincing little strain when rising to the piercing climaxes. I was also impressed by Mr. Maroulis's quietly intense performance as the obsessive Dr. Jekyll...Statuesque and beautiful, Ms. Cox brings a suffering dignity to this cliché in corsets. More important for those who have come to hear a pop diva do what pop divas do best, her dark, lustrous voice does nice justice to her character's signature song...Unfortunately there's no way to digitally airbrush away the hokum that pervades the whole show, like the ample stage smoke puffing away throughout the proceedings, giving a most commendable featured performance as the fabled pea-soupy London fog.
