Story centers around a mother with severe dissociative identity disorder. Toni Collette gives incredible performances as all the various personalities. A dramedy that leans more into the comedy side of things. 3rd season just started, but starting from season 1 will explain A LOT that you may otherwise not understand.
I get a kick out of the one-liner's on this show. It was created by Diablo Cody, the same writer who wrote Juno. So, if that movie entertained you at all, it'd be worth it to check out this show as well. It's not exactly award-winning but it is entertaining.
