I see your point but to be fair it was his first book series. I think he startet writing them in his teens, i would say knowing what i kown now he didn't planed it thru and also its like a mashup of other popular things like Lotr but reading them in my early teens i was really invested and loved them :) I also read 'to sleep in a see of stars' and there the plot was definitely more coherent but it also had some stretches. But i took my nostalgic glasses out of a box and read Murthag and at least with them it was really good
