It is generally better to “show, don’t tell” in films. Well the PT oftens fails to do either! No only do we not see Anakin and Obi being good friends, we see them somewhat antagonistic towards each other!
It also wastes it’s time introducing things that go nowhere: like the whole Sifo-dyas subplot. It is because there was no
overarching plan. Lucas was making up the films as he went along. There was a very clumsy idea of attachment being what leads to Anakins fall…but it never resonated with much of the audience.
Frustration with the Jedi being somewhat helpless to cure the ills of The Republic would have been a much better angle for explaining his fall.
