This doesn't really make the Smurfs
special, you know.
You could say the same thing about the dwarves in Snow White, or any collection of "themed" characters for that matter. The alien races in Star Trek are another good example: the Ferengi are avarice, the Klingons are wrath, the Dominion and the Romulans are all about power (and Captain Kirk is lust). Other, less commonly-featured races stand in for the others. Humans cover most of the bases at once (except maybe avarice since they usually don't use money and have energy for free).
