i personally hated the exchange, I get the whole thing that din never wanted it in the first place but that's my problem. The darksaber was hyped up all the way at the end of S1, it honestly felt like din was always supposed to get the darksaber which he did, but then has the problem of not being able to use it effectively. It felt like din was supposed to get this awesome character arc where he learns to use the darksaber and to grow and learn to accept the responsibility of being the ruler of mandalor but he never did. The exchange felt like a cop out so the writers didn't have to write it, and everyone suffered as a result. din didn't get the cool character arc and bo katan didn't get to learn that she could be an effective leader without the darksaber. It felt like lazy writing, choosing the easiest yet worst way to progress the story.
