If someone took the time to re-dub all the Gungans with proper English, as well as re-animate Jar Jar to be less goofy, then I think the Gungans could be a pretty interesting part of TPM.
When I look at some of the Doug Chiang concept art for Jar Jar and the Gungas I can’t help but feel that they were a real missed opportunity.
Then again, “many good and interesting ideas poorly executed”, is a pretty decent summary of the PT in general.
