There was a bit of Broadway in primetime last night with NBC’s Smash (1.1/3) returning for its second season. However, it was a hard landing for the musical drama: The two-hour premiere was down 71% from its Season 1 debut on February 6, 2012. That premiere got a 3.8/10 among adults 18-49. Granted, the show didn’t have the powerhouse lead-in of The Voice it had last year, nor the Super Bowl promotion, but it cratered to 4.47 million viewers from the 11.4 million who watched last year’s first episode. Hitting a series low, Smash was also down 39% from the 1.8 rating it got for its May 14 season finale.
