While I love each and every cast member as individual, the casting crew did not do enough screening and interviews with them, otherwise we would not get this mess. It's important to cast people with different ideal types and romantic expectations to give the show more variety of interactions. We did not get it here. It was one man and one woman story with 6 "supporting characters".

All that could still be saved if there was some kind of directing involved - forcing the cast members to go on dates with different people. Asking them to pick someone they have not been on date with yet, or random dates, or making contestant pick dates for each other.

Still, the first half of the show was great and I'm actually far more interested in watching After Signal than I was finishing Heart Signal 4.
