Never again having any character flaws whatsoever, meeting, defeating, and having babies with a hot redhead, being the greatest, bestest, strongest, and wisest teacher and jedi ever, etc.
It really does explain a lot about how Crossing views this series that what is a very clear, child friendly metaphor for self improvement and becoming a more fully realized and aware version of yourself is flandarized into something that seems so impossible and unattainable.
It reminds me a lot of people that tear down Superman for being unrealistic, or ask why Batman doesn't execute his villains. Quit applying your IRL mediocrity to hero stories for kids just because you don't believe in heroes, or in the case of Luke Skywalker, that someone could make a lasting, permanent philosophical change in their life.
