Since we have so many "newbies" here (and since the question has never been posted as a thread), name your most and least favorite "Little House" character. Try to name just one of each! Regulars, bit players, and one-hit wonders are fair game. And justify your answer!
Most favorite: Nels Oleson. An all-around great guy; he just ruled whenever he would let his wife have it.
Least favorite: Mr. Montague. An annoying, unnecessary, and just-too-weird addition to the cast.
