Have you ever heard of Karl Pilkington?(He's a friend of Ricky Gervais, and Ricky discovered his dry, unintentionally hilarious wit when paired with him during a radio show Ricky and Steve Merchant did)
In any case, Karl once remarked that Dogs were just lazy. Ricky asked what he meant, and Karl said: "Look, we are all supposed to have evolved at the same time, right? Well, dogs have had just as long as humans have had. If they just got off their arses and worked harder, they could have cars and houses and mobile phones by now too..."
The only reason i mention it is that, real world aside(Where Ewoks, no matter how out-of-place in the SW world, were a great marketing idea to sell teddy bears), even though they look like teddy bears, they appear(In ROTJ at least), to be the apex predator on the forest moon of Endor, lol.
I'm not an apologist for them. But in relation to some other characters from SW, the Ewoks aren't too bad, lol. In the words of Tim from Spaced(Our very own Unkar Plutt), "Jar-Jar Binks makes the Ewoks look like F*cking Shaft!"
