The ewoks. Whatever underdog metaphor he was going for kind of got lost in the cheap, klutzy execution. It all just looked like people in ill-fitting suits. And if you think too much about it, they didn't really do much of anything. They made some racket so Chewie and Han could do the important stuff. The team could've been captured, thrown in a cell, then somehow rescued by R2 and 3P0. Then, like they planned, the team blows up the generator Dirty Dozen style. We wouldn't even need the little bastards.
