I really was just trying to get through it the first time. Really liked lightsong. However I had already read whatever cosmere books were already out at the time and it didn't live up to mistborn or stormlight. But later when I was reading all of the cosmere again... I really enjoyed it. And then read it a third time later and loved it even more.
So to everyone that didn't care for it, try it again. I don't know what it is about warbreaker that makes it more likable each time.
