Terrific concept executed really well.
Pairing up your sibling on a dating show was a bold move and it paid off. This aspect of the show was very heartwarming as we see the interactions, some sweet and caring others snippy and defensive, evolve as the show progressed and the sibling dynamics became very supportive of each other.

The panel were at times hilarious. They resonated with the unfolding drama and their reactions disclosed how their own dating past had unfolded. It was fun to guess along with them about which siblings were related and who fancied who.
The participants are to be commended. Spending two weeks living together in Korea and a week in Singapore with 4 potential dating partners may seem like a terrific opportunity but it has its drawbacks. These individuals are constantly miked and on camera so they know every nuance is being viewed and critiqued by the audience. There were times when the interactions were completely off the cuff and natural and some netizens moralised and pointed fingers. Personally I think the 'flaws' were the honest charm of the show. Loyalties switched and surprising pairings occurred keeping us the audience keen to know what happens next.

The format was also clever as new rules were introduced giving everyone a chance to interact closely with the other potential partners. The singing duet talent show was fabulously entertaining. The flash back videos of each family brought tears and deeper understanding of the sometimes difficult challenges the participants had faced.

Random Note: does anyone else see Yon Woo's likeness to a younger version of the American actor Ben Afleck? I was reminded of the character he played in Gone Girl who keeps smiling at all the inappropriate moments and is wrongly accused by the judgemental public.
