I agree with the reviewers who give a lower rating because of the first episode (which essentially tries to cram too much in at once), however if you give the show a chance it does develop into something much better.
If you are a fan of light hearted dramas such as 1000 words - i think you will like this. Several of the actors are established Aussie actors who you will recognise if you have watched many other recent dramas - including Five Bedrooms.
The story revolves around the RFDS and the crisis they face, however the show deals with this in such a way that you can't help connect with those affected.
It is sweet and heart felt and a nice light easy watch. It keeps out modern politics and all the social nonsense you watch TV to avoid.
The only annoyance with the show is the English Doctor's son. He is just a whiney child who acts far younger than his age. The show doesn't really connect with his character, and the actor who plays him is so wooden that you are glad of that !
