I didn't mind that so much - I was a huge Dark Empire fan. But having Rey Palpatine ultimately bring balance did make the first six episodes rather pointless.
Rey did not impact anakins arc whatsoever, Anakin brought balance to the force for a moment in time, that was his purpose he wasnt going to live forever so he could not keep it in balance forever. The moment he died the balance started shifting. The living force is always in flux always in motion its endless. Any changes in the light side and darkside exert pressure on the force itself. I dont know why people view the force as something that would stay in balance forever after one heroic act at one point in time. You cannot eliminate darkness from the world forever with a single act. New darkness will always rise, the force seeks harmony and balance with this darkness not the destruction of it.
The sith and jedi both caused aberrations in the force because they both have extremist views of how it should be used, who is chosen to use it, how they are to behave and what they are to believe in. These extreme philosophies (sith and jedi) resulted in both sides creating an unbalance in the force. This is why luke said it was the jedi hubris that caused them to believe that the force belonged to them it does not, it does not favor sides -it is neutral. It is not the jedi’s to mold or to change its rules to fit their own philosophies. The Jedi disrupted the lightside of the force as much as the sith did the darkside but in different ways as illustrated by how the jedi and sith code deviate from the original decree. Their dogmatic beliefs also led them to misunderstand the prophecy of the Chosen one, to them balance meant wiping out the sith and completely ridding the world of darkness which was obviously not the correct interpretation (they are the ones who were wiped out, it was their corruption of the light that also needed to end along with the sith to bring the force back into balance)-
The force code (Balance)
Emotion, yet peace.
Ignorance, yet knowledge.
Passion, yet serenity.
Chaos, yet harmony.
Death, yet the Force.
The jedis distorted version (Unbalance corrupted by lightside principles and dogmatic views)
There is no emotion, there is peace.
There is no ignorance, there is knowledge.
There is no passion, there is serenity.
There is no chaos, there is harmony.
There is no death, there is the Force
Strict dogmatic rules and hubris led them to shape and distort the “lightside” into something it was never supposed to be, much like the sith and their corruption of darkness. The jedi’s code does not allow for balance, their vision of balance is what led to their downfall. A complete rejection of anything they deemed to be dark or sinful (including love and attachment - you cannot reject these good emotions and remain balanced or in harmony with yourself).
