That would have been a good scene to leave in. The role of R2D2, C3P0, and Jar Jar as the point of view/”narrators”/observers/story tellers of the entire saga was lost with Jar Jar being cut out. As the lowest level of beings — one who can’t talk, one who doesn’t know what’s going on (memory wipe), and one who is a simpleton — was a really interesting device that maybe should have been made more prominent (as in Ep. 4), not less (as in Ep. 3). Although C3P0 does partially redeem himself with telling the entire story (as far as he remembers) to the Ewoks in the end. It would have been nice to see how Lucas actually intended to end the series.
