We missed the suprise in ROTJ!
I love all the movies of Star Wars. I think TPM and AOTC got 10/10.
But ever since ESB's "No, I am your father" twist came into the saga, it seems George wanted to suprise us again.
Allow me to explain.
At the start of ROTJ, Vader explains the Emperor is coming to the DS. He explains how he's not as forgiving as he is.
I think George wanted to show us that a new bad guy is coming.
We we saw the Emperor, we thought he was defensless...my arse!
He had lightening bolts coming out of him left, right and center. I think that was the suprise of ROTJ. The Emperor's lightening.
But it was taken lightly because it didn't surpass the "No, I am your father" scene.
