Its an interesting series and not at all what we anticipated when we first started viewing. We thought it was going to be a adult medical drama, and it is with some very keen, realistic medical drama but its actually a "fish out of water" storyline of a young doctor exiled to the local primary school due to a social misunderstanding in a medical situation while an intern at the local hospital. Made comic by the fact he possesses no interpersonal skills whatsoever even with adults, let alone children.
It is difficult to determine who the show is targeted at. I think many adults will find the main setting and focus of the drama being a primary school (Gr 1-6) a bit tedious at times. The acting is good and in fact the child actors are superb and phenomenally convincing in their roles. But we could not see young people watching this series on their own: too adult for children and too juvenile for teens. We landed on it by happenstance & misunderstanding of its focal point but that's not really the way to market a series!
All through the series we were afraid the writers would go the dreaded route of putting the 2 main characters into a "relationship" and thankfully that was never touched.
Is it worth watching? Yes, and it has good entertainment value as well as interesting medical drama. You will need to be in the mood for a different flavor of serial drama and have an open mind but we enjoyed it.
