I've said from S1 that I really like the recoupling format - what it does especially is enhance the "social game" aspect of this show in the sense that if you're not coupled up, you need to strike up a bond with someone to convince them to pick you (like the position Niall/Samira/Alex find themselves in)
What I STILL wish they would do is cast people who are
legitimately and unequivocally there just to play a game. As in, they're not there for love (they might even be in a relationship!) and they just want to play someone in the hope of winning £50k
Then and only then may the split or steal twist on finale night at last deliver the most iconic TV moment this decade
