Smash crashed and burned in its much-hyped, two-hour, revamped return, drawing a mere 4.5 million viewers and a 1.1 in the adults 18-to-49 demographic Tuesday. That's down a whopping 71 percent from its post-Voice series premiere last season and almost 40 percent down from its season finale. It's also well below the 4.98 million viewers and 1.8 that Parenthood averaged in the 10 o'clock slot in the fall.
