Just finished a video about this very subject. But I have to say, even though I've made the pro-Jar Jar argument before to friends and whoever, going through the movie for clips and actually seeing it laid out in front of me on a timeline for a week or two made me realize a) how rich the character's story arc actually is and b) how much nuance Best and ILM brought to his portrayal. The instinct is to compare Jar Jar to, like, Ruby Rhod or something. But there are a number of scenes in the movie where he drops out of "comic relief" mode and into something completely different. And even in comic relief mode he usually has an extremely clear POV, feeling about what is going on, etc etc. A number of little grace notes throughout -- for instance, I really like the way he talks to Anakin as a fellow outsider in the Coruscant sequence. (I also laughed more at the comic relief bits while making this than I usually do, which may be because I was seeing them more in light of his character and less of just "antics."
