Previewing NBC's fall offerings has been a long process. First I gave you Community and Trauma, then Parenthood. Now, I have NBC's second medical drama that's premiering this year: Mercy. While Trauma follows first responders in San Francisco, Mercy follows nurses in a hospital in New York.

While it's true that I've seen the pilot and should be able to give you some insight into what to expect when it premieres (Wednesday September 23, at 8 PM ), the fact is, every single thing you need to know about Mercy is summed up in its synopsis:

"Nurse Veronica Callahan (Taylor Schilling) has just returned to Mercy Hospital from a tour in Iraq and knows more about medicine than all of the residents combined. Together with fellow nurses Sonia Jimenez (Jaime Lee Kirchner) who turns the heads of everyone at Mercy hospital and Chloe Payne (Michelle Trachtenberg) a naïve newcomer who learns to deal with the difficulties of working in a challenging and sometimes unsettling profession, they navigate the daily traumas and social landmines of life and love both inside the hospital and out."

NBC seems to be sending out their screeners in dribs and drabs, so I'm making my way through their fall offerings very slowly. I've already given you previews of both Community and Trauma, and now we've got Parenthood, a new series based on a movie that was already turned into a series nearly twenty years ago. Who says Hollywood is out of ideas?

Parenthood is basically a less-melodramatic Brothers & Sisters. It follows the Braverman clan, a family in Fresno made up of four siblings: Adam (Peter Krause), Crosby (Dax Shepard), Sarah (Maura Tierney), and Julia (Erika Christensen), along with their children and parents, played by Craig T. Nelson and Bonnie Bedelia. They all have their share of drama, but at the end of the day, they're all brought together in the most suburban of pursuits: Little League. Say it with me now: "awwww."

In the yearly scramble to pick up pilots, renew old shows, and dispose of last season's weaker offerings, ABC is shorting 80s sci-fi favorite V.

The original 1983 miniseries featured a race of stealthy, guinea pig swallowing lizards from the stars taking over the world with fascist strategies reminiscent of the rise of Nazi Germany. The following year's TV series dumbed it down a bit and became a weekly battle between freedom fighters and creepy aliens.

You can catch the upfront trailer for V here. It looks a bit like ABC is being invaded by Independence Day -- though Independence Day looked like it was being invaded by the original V. Fortunately, these new invaders bring Firefly's Morena Baccarin (right) along for the trip as their spin doctor.

Coming off a strong 2008 season, CBS is taking some bold moves with their new season program schedule. As we wrote earlier, there are four new dramas, a sitcom and a reality show in the mix.

The big news is how it's shifting around some hit shows on Monday and Thursday, while standing pat on Wednesday. Here's what we know right now...after the jump.
