I think that's kind of a weak assessment. Yeah, there are some similarities but you're cherry picking from three different star wars movies to compare them to this movie. Yes, there are some similarities but its not really ripping on SW at all.
I mean, there's also Sam who doesn't want to take his father's company and just dicks around during his youth. By the end, he has come to realize his errors but realizes that he can't do it on his own. He ends up passing the company on to the family friend older mentor character. Obviously, this movie is channeling Billy Madison. See how easy that was?
haha, yes i see your point. Maybe I am trying to make these movies more similar than they truly are. However I feel there are many likenesses.
