Alien species help to define the science fiction genre in the same way that elves and dwarfs help to define the fantasy genre. In a sci-fi work the aliens can be enemy monsters, helpful companions, or remote observers, just to categorize a few options. With a few exceptions, however, the heroes of the works are humans. Thus the aliens provide the trappings for the setting more than actual content. In Star Wars Lucas put the aliens on display at the Mos Eisley cantina but outside of that scene we really only have Chewbacca to provide the alien flavor. The fans latched onto those aliens, aided by Kenner action figures, and fans being what they are, they spun an Expanded Universe of tales about those aliens. This is the sort of obsessive behavior the sci-fi and fantasy fans are known for displaying.
As previously touched upon, the standard for the genre is to assume that all members of a species are alike until proven otherwise. All Bith love music and make great musicians. All Wookies are poor losers. So on. To some degree these stereotypes are why we love the aliens so much, but then it is in our nature to play with the stereotypes to develop more cool characters.
This should be one of the coolest things to ever come out of a Star Wars property. Cad Bane, space gun-slinging bounty hunter just annoys me all to Hell.
Assessment: Maybe Star Wars is a big sandbox for us all to play in (until the big bearded kid kicks down the castles and takes away your pail and shovel) but this Clint Eastwood-Duros-With-No-Name wannabe just doesn't fit. There might have been a time when he did, but that was before the whole thing became about Jedis and Sith all the damn time. Cad Bane appeals to the kiddies, but then one is left to wonder why given that the Western in general, and Clint Eastwood's spaghetti westerns in particular, are not relevant to a modern young audience.
As Mr. Spock would say, "This individual demonstrates belligerent behavior and an alarming lack of regard for the law." Or the law of fashion, Spock. I mean it. What the hell are those things on his cheeks? I've seen plenty of Duros before and he's the first with cheek pipes. Damn, Lucas, you suck.
Stay tuned for more aliens and Halloween fun.
