While the series has numerous typical NYC characters coming and going, the core three of Martin Short, Steve Martin and Selena Gomez are what makes this series tick. Its beautiful watching Martin's character come alive after suffering some lonely elderly depression. Same with Martin Short's character. While he obviously portrays his life as something much more, you get to really see how much his new friends mean to him. Selena Gomez is perfect in her role and especially how she interacts her "youth" with there "age". (I think a lot of people are underestimating her role. She is supposed to sound monotone!). She, like her two male counterparts, is doing some soul searching herself and it is warming when she finally admits how much those old guys mean to her.
