I have watched the other 2 productions and I feel that they are improving the format with each show.
I think the people who come on the show are very emotionally brave. They are about to be filmed during intimate conversations with their exes and be judged by the viewers.
We, as the audience are given a ring-side view of all these individuals and their past relationships are revealed later in the show so guessing the pairings is intriguing.

I find it fascinating to watch those who come on the show with a clear goal in mind find their determination failing as jealousy shakes their resolve. Few people, I believe, can handle seeing their ex enjoying and thriving in the company of another unless they had already handled a mutual agreement to split up as a couple.
This show sends the individuals into past reflection and has numerous contrivances to trigger this. I personally think this is a good thing because it gives them a chance to appreciate what was good in their relationship and what may have caused the breakdown.
Their are many shifts in the couple emotions and as a viewer, or even one of the hosts, it can seem easy to comment on where the individual is failing to communicate their feelings. As a participant the burden of emotions warring with their logical mind can elicit some poor responses and regrets.

These are real people and even if some participate to perhaps get higher media cover they are reduced to an individual looking for love.
I also like that we get to see that pairings are not always obvious. Brief connections can be as painful, or joyous, as longer term established relationships and offers us a chance to think how we might have reacted in this.

After all the exaggerated emotional dramas I have been consuming this program is refreshingly 'real'.
