Ronnie you should appreciate the situation Lucas was in while he was making the prequels. It’s eerily Similar to where Wenger is in his career.
They did not make it or present it, but it should be.
Qui Gong did not teach Anakin that much, it was Obi Wan, like a father figure, raised him and taught him for years. They must had a very close bonding and relationship.
If there is one thing to complain (yes…), I have to say why Luke turned up to be a senile old man in the Last Jedi, under Disney???
When he was young, he was already strong enough to sacrifice himself to turn his father Vader.
After all these years, he must had seen/experienced a lot, must had talked to Obi Wan, Yoda, Vader’s force a lot and understood the balance of universe. Kylo Ren betrayal should be just a peanut to him.
