Awake didn't open to huge numbers for NBC, but it wasn't a complete nightmare.

The long-awaited drama's series premiere bowed to 6.2 million viewers and a 1.9 ratings in the adults 18-to-49 demo on Thursday. That's a massive 44 percent and 58 percent improvement on NBC's season average audience (4.3 million) and rating (1.2), respectively, in the 10 o'clock hour. It is also the network's best debut in the slot all season, following the short-lived Prime Suspect and The Firm. The caveat, though, is that CBS and ABC aired reruns.

Idol: Meet the Top 13

With nemesis and recent conquerer The Big Bang Theory in repeats, American Idol took advantage, pulling in its biggest Thursday audience all season for its two-hour-long unveiling of the Top 13: 18.3 million, along with a 5.3 rating — both up about 18 percent versus last week.
