If you moved the throne room scenes to Coruscant Palpatine and Vader are in no immediate threat.

When I watch the movie, that's not what I'm thinking about. Also, isn't that make sense there in no threat. Palps should be smart enough to learn from the destruction of the first DS explosion. Palps was smart enough to play both sides of the coin in the PT.

This film isn't about the DS explosion at the end of the film. Vader and Palps are already dead, so what's your point here? I'm probably misunderstanding you.

Lastly, I think the palace in space crap is nonsense. Palps should be on Coruscant, like most people assume he is. Not floating around in space, talk about putting yourself in danger.
