I wouldn't go as far to say that they are unliked (or "unfavourite" I think the term was). I suppose, because they all had a relatively short shelf life within each of the movies, there wasn't much to link to so most fan just didn't pay them much attention (not including any reappearances in the TV series mind).
Eh, I dunno. I mean, I don't hate characters, and they are kinda cute, but their use as a plot device is so blatantly executed that's it hard to overlook for me :huh:
