I’m all for making ROTJ more nasty but I would do it by adding more gore to the Ewok’s camp. Showing dead and partially eaten stormtroopers etc.
Something like this?
…
On the other hand, something like the above would be more at home in Return of the Ridiculousness.
Carrying this over here before it gets forgotten.
The dialogue from the film could be used for a stormtrooper voice.
