oh ... and the jar jar tirades ... keep in mind that jar jar and his people were probably a bit less annoying than the ewoks or c3po. remember all c3po's insipid comments during the original trilogy? he was put in for comic relief. so war jar jar.
also ... a recurring theme of lucas' star wars universe is (ironically) a taunt against technology. think about it. who defeated the empire in the final battle? a single jedi w/ no major weapons and a force of ewoks (talk about primitive ludites). they took down the most technologically sophisticated galactic power. the death star can destroy an entire planet ... but a band of ewoks can help bring it down.
the battle in which jar jar's people defeated the robot army was similar. outnumbered, they fought bravely. and they used slingshots ... so it was in keeping w/ the ewoks motif, but a bit more realistic (since the slinghots threw energy balls of some sort). but notice their armor ... it was samurai fashion (esp when you saw their "cavalry") ...and army based on honor and simple courage defeated battle droids.
just like the original trilogy ... the first was clearlygeared toward kids. but if you look at it carefully enough .. you see the hints of darkness. for example, look at anakin's face when confronting the jedi tribunal. if you look closely, you can already see that he thinks he's better than them. you can already see him going "dark side".
