What would happen if you put couples, that already have zero trust, confidence or love for each other in a reality show that does everything it can to create drama? Apparently, this.
Couples range from "dude who cheated his gf six times already" to "dude who cheated, but not really, coz it was with an escort and that doesn't count". Put half of them in isolation and the other with bunch of singles paid to sleep with them, include couple manipulative cuts, extremely unlikable moderator and mix in a premise of lie detector that is not backed up by any explanation or actual science (but that is actually determining the cash price for some reason) and a gem is born. That gem being the cheapest bijou, but Chinese scam shops will still title it "gem" so...
Show isn't boring per se, but it is definitely a second, maybe third or fourth screen watch. Once you start thinking about. The people there or the premise itself, it becomes... annoying.
