It's a Jason Katims drama. This means if you liked the storytelling of Friday Night Lights or Parenthood, this will probably be in your wheelhouse, even if it has the family serialized drama hallmarks of a chick show.
He also helmed Roswell, Boston Public and My So Called Life.
Generally [ie, the Katims blueprint] the scene is very talented and photogenic actors playing romantic and sibling family components and encounter life trials viewers can relate to as a group.
Specifically [and this spoils the early storytelling a bit if you don't want to read it]
So as you see, lots of details to draw on. It's blatantly heartstring-pulling and occasionally schmaltzy. But it's also expertly done, and well acted by attractive people.
One of those shows where it's not so much WHAT it's about, as it is HOW WELL it is about it.
