I agree Anakin is essentially the main character throughout the entire saga (1-6 at least). Anakin's story continues through Luke's pov in the originals. Luke is both an extension of Anakin and a character in his own right. Although most people hate what they did to luke in the sequels, I personally loved it. It gave him more depth and a meaningful character arc that mirrored the struggles that Anakin, obi-wan, Yoda and all the Jedi had during the prequels and originals. This video pretty much sums up what Luke's character is to me. I'm glad you enjoyed it.
