In a Variety article which, as is typical, smooches up to the networks about how well they're doing, 4 new ABC shows are called "quasi-hits" (V, FlashForward, Cougar Town and The Middle). I guess calling them anything less might anger the potential Variety advertiser that is ABC.
Absent smooches, I think it's quite likely that one or more of those "quasi-hits" will fail to survive until next fall.
You can watch the same ratings trends I do in the ABC show Renew / Cancel Index posts, but here's my current guesses on all 4 shows.
With this adults 18-49 ratings trend (4.0, 3.7, 3.0, 3.1, 3.1, 2.7, 2.6, 2.6, 2.4) it's my odds on favorite in this group to fail to survive into season #2.
It fell sharply after its premiere, but the last two episodes tallied 3.1 adults 18-49 ratings. That's worthy of some hope. Now, it will be on an extended hiatus. It's ratings on return will tell the tale, the past ratings will be all but meaningless.
3. The Middle
Paired with the loser that was Hank, it looked like it might be a goner, but the ratings picked up when paired with even the repeat of a show people wanted to watch. It's chances for a second season are definitely better than even.
4. Cougar Town
It was a disservice to Cougar Town to put it in the same list with those other three shows. With its ratings to date, there is abolutely no chance it doesn't come back for a second season barring some non-ratings event.
