Alignment could be confining, but it was also defining and a vehicle of storytelling. Even the likes of Sauron seems less daunting and interesting when viewed through a prism of postmodern relativism. Only time will tell how this impacts storytelling in a setting that at its core was driven by the struggle between good and evil. Hopefully though, the writers avoid more contemporary tropes becoming a focal point.
I wasn't suggesting post modernism, but that alignment is so contraining that it kills naunce and reducing characters to one dimesionality.
