Well, yeah, some puppet do look fake. Take the ones from Mr. Rogers's Neighborhood. The King and Queen serve their purposes well, but I'd never see them on the street and believe they were real. Of course, I'd never see them on the street at all (unless I'd taken some bad death sticks ^_~). As for the Star Wars puppets, which is what I assume you're talking about... well, some of them looked kind of fake, too. They all have their individual problems. But the two main Star Wars puppets... Jabba the Hutt and Yoda... well, I have yet to see a CG rendering that does either of them justice.
