Jang Hyuk and Jang Na Ra, both on their own or when together, will always deliver. Their experience, especially together as an on-screen pair is definitely needed in tvN's Family: The Unbreakable Bond (패밀리). And that's because an interesting concept and lots of potential are unfortunately held back by a strong tonal imbalance that does what it can to pull you out of the action instead of reel you in for the ride.
