Personally I really liked the theme of balance being something has to be actively maintained. That’s how things tend to be in the real world, after all, and Star Wars is all about vaguely applicable moral lessons. The importance of keeping up the work of previous generations - and if possible, surpassing it - lest you forget the lessons of the past is one of the things the sequels manage to convey (especially in TLJ) I think.
Agreed. It would be a shame to remove Anakin’s line. It’s there to signify that he was in fact the chosen one, but due to the unforeseen and unnatural abilities of Palpatine the will of the Force was delayed.
