The CW’s Smallville and Fox’s Fringe dipped in the ratings Friday night, even as NBC’s Friday Night Lights rose.

Perhaps the Easter holiday weekend was kryptonite to the Man of Steel, which fell 10 percent in the demo for an episode titled “Booster.” Supernatural remained steady with the week before and ABC’s Shark Tank slipped 7 percent from last week’s season high.

CBS won the night with Girl’s Night Out: Superstar Women of Country special (8.4 million viewers, 1.6 preliminary adults 18-49 rating). If it seems like there’s a ton of country music specials and award shows, you’re right — it’s because they always manage to pull a decent rating.

ABC and NBC tied for second, with Shark Tank (4.9 million, 1.4) followed by Primetime‘s hidden-camera-prank-show-pretending-to-be-a-news-program What Would You Do (4 million, 1.1) and 20/20 (4.4 million, 1.2).

NBC’s Lights (3.8 million, 1.0) was followed by Dateline (6 million, 1.4).

Fox aired a repeat and Fringe (3.5 million, 1.2), taking the steepest tumble of the evening, down 14 percent.

The CW had Smallville (2.2 million, 0.9) and Supernatural (2 million, 0.9).
