Sorry for the wait, but here's part 2.
None. NBC continued their path of failure with no new show getting high ratings. I still consider NBC a broadcast network on part with Fox, CBS, and ABC, so it's clear none of the new shows are doing great. If I were to revise my standards and consider NBC with CW, then that's another story.
Community started off very well after The Office, retaining much of the audience, but the move to 8 PM hurt it badly with current ratings hovering around 2.0. It's in a tough timeslot, but 2.0 is hardly anything to cheer about.
Trauma was a big time flop. The episodes are very expensive, and NBC promoted it quite a bit. The critics hated it and so did the majority of viewers.
Mercy was given a full season pick up, but with ratings floundering below 2.0, it looks like NBC made a mistake. The critics also hated Mercy, lumping both new medical shows in garbage pile.
Heroes fell again and is now staying around 2.4 which is on the high end of NBC dramas. With all the other money attached to the show (international, syndication) Heroes should survive. Even after all the things the cast and crew were saying about how great the season was, the critics didn't even care, choosing to ignore a show that had burned them before.
Parks and Recreation rebounded after dropping very low last year to get around the same ratings as Community. I think the two will be in competition for renewal.
Law & Order was relegated to the Friday slot which almost certainly meant it would stay there to die quietly, but the ratings have risen to where it can compete with the CBS dramas. Somehow it actually has a good chance of survival.
