Last night’s ratings are full of interesting moves as Thursday shows signaled some intriguing shifts. Here’s what happened:

— Fox’s X Factor dipped (10.8 million viewers, 3.6 adults 18-49 rating). The judges’ homes episode that was pushed from Wednesday due to championship baseball overrun fell a little from last week. Were viewers confused about whether the show was on tonight? Did the break in momentum hurt the show? X Factor always improves from its preliminary morning rating, but it will still fall a tad shy of last week.

— CBS’ Person of Interest (11.9 million, 2.7) improved for the first time. Just a 10th of a point, but still, always good to see a new show apparently find its bottom and bounce up.

Charlie’s Angels (6 million, 1.3) went up. Yes, you read that right. For the first time, massively under-performing Angels went up — yet only by a 10th of a point and its number is still really small. (Did guest star Erica Durance help?) The word on the street was that Angels would get the axe today. But networks hate to kill a show right after its number goes up, it leaves executives tossing and turning wondering if the show was about to stage some unlikely epic turnaround. Too little too late?

— NBC’s Prime Suspect (4.5 million, 1.3). NBC badly wants this police drama to work but it’s just… not working. Despite running repeats on Monday nights, and despite the network ordering six more scripts as a sign of faith in the drama, the NBC freshman series hit a new low. Meanwhile, new comedy Whitney (4.2 million, 2.0) fell 13 percent too.

— The CW’s Vampire Diaries (2.8 million, 1.4) went up. In fact, VD outperformed Charlie’s Angels and Prime Suspect… which, of course, says more about Angels and Suspect than it does VD. But still — bragging rights! Secret Circle (1.8 million, 0.8) was steady.

Overall: After seeing most shows steadily dip since their premieres, Thursday had several programs rising — a least by a little. Fox won the night with Factor. CBS ranked second with Big Bang Theory (13.3 million, 4.4) down a tick and The Mentalist (12.3 million, 2.5) off 7 percent (one analyst pointed out that Big Bang‘s repeat at 8:30 p.m. beat X Factor in the same half hour). ABC had Grey’s Anatomy (9.7 million, 3.6) climbing 10 percent and Private Practice (6.7 million, 2.4) up 14 percent. NBC’s Community (3.8 million, 1.7) rose 13 percent, Parks and Rec (4 million, 2.1) was up 5 percent, and then aired The Office (6.1 million, 3.2).
