Really the intense force powers and lightning should not be shown till ROTJ. If the order of the films is to truly be 1-6, the action and tension needs to build up on eachother.

I agree with this.

Many people point out how the PT ruins the revalation that Vader is Luke's father in ESB, but they don't mention how shocking (no pun intended) it was for the Emperor to suddenly start electrocuting Luke right out of nowhere in ROTJ.

I think it's important to retain that shocking moment at the climax of the final movie.
