According to TVLine, "Supergirl's" Season 2 premiere clocked in with 3 million viewers and a 1.1 18-49 demo rating -- up triple digits from last year's show in the slot, "Crazy Ex-Girlfriend." The high ratings solidify "Supergirl" as the most-watched Monday night show on the CW since a 2008 episode of "Gossip Girl," with the best 18-49 rating since a 2010 episode of "90210."

While "Supergirl's" ratings are pretty impressive for the CW, the show of course fared much better on CBS, as the Season 1 finale drew in a whopping 6.1 million viewers and 1.3 rating in the 18-49 demo.
