The ratings are scarily bad. I hate that ABC put it in that timeslot. Still ABC had 2 HUGE bombs for new dramas this fall with Lucky 7 and Betrayal that are doing quite a bit worse than Wonderland for the slots they’re in, so that helps Wonderland’s chances. Nashville also has about the same ratings as that Wonderland number but in a more favorable timeslot, plus I think at this point ABC knows Nashville isn’t going to catch on, so they may also choose to axe that instead. I do worry about the budget of Wonderland making it harder to keep if it’s just skating along.
Here’s my theory. ABC moves it to Sunday at 8 when Once has its mid-season hiatus, which was the plan in the first place before changing it to a full order. Even if the ratings absolutely tank on Thursday, my guess is they shelve the show but then put it back on when Once hits hiatus.
