Sorry to say but only Fans of Luke see him as that way , there are atleast a hundred other characters who could be considered main characters .
I still think Luke's going to be the most powerful. Because he's the main character. It's either going to be him, or the guy he passes the torch on to. Personally, I prefer Luke being the best. Luke or another Skywalker. The movies have been about the Skywalker's so I think it should continue like that.
I look at StarWars like I look at Marvel and DC . Its uncreative , unimaginable people who seems too Fanboyish to have the ability to break past Luke Skywalker , the most predictable Character in any Comic .
So your welcomed to like these Stories that surely always end almost the very same way everytime , I like my stories to be writen by people who are able to have imaginations and be creative .
By the way , where is good old ProfessorWalsh, I know hes a BIG EU LUKE SKYWALKER Fanboy, hope hes doing ok and having a happy Holidays !
