I will admit, the only reason why I started watching this show was because of Jewel Staite, and wasn't expecting much, but I was pleasantly surprised by how well it was made.
The show follows the lives of a group of friends as they try to make it in LA. This isn't an entirely new concept, but what sets this show apart is how all of the characters are very believable. It's a hard industry that's hard on the people trying to earn a living off of it, and this show shows that side of the story.
Fair warning, this show seems to be made for people who have made parts of their lives a part of the industry. If you're an actor, improviser, singer, comedian, producer, or ever tried making a career somewhere along that path, you will completely relate with all the characters as they struggle for their "break." If not, it's still a decent watch, but it may not hit as hard.
