“Even though you may imagine that ‘So You Think You Can Dance’ is just a dippy ‘American Idol’ also-ran, even though you’d rather iron your soft pants and regrout your tub than watch dorky teenagers waltzing or, worse yet, putting on ‘funky hats’ and ‘hip-hopping’ or whatever they call it, this show really is worth watching. … Each performance, whether it’s a contemporary extravaganza of tangled limbs and faux-passionate emoting or a faux-passionate Argentine tango or a romantic, graceful faux-passionate waltz, depends on the real passion of the dancers involved.”
