The Waltons/Headscratchers

• Is John-Boy a bit of a Marty Sue for anyone else? It seems like several episodes climaxed into him solving the problem-of-the-week. I realize the show is based on his memories of the family (and he's Earl Hamner' Author Avatar), but with that being the case, he sure does talk a lot about him taking care of a lot of people's problems. Also, Rev Fordwick goes away for a weekend...and he picks John-Boy to do the sermon? Really??
