Some episodes there are teenage issues (dating, kissing, impressing, etc.) There can be a lot of making out, but it is a great show.
There is an episode where the grandpa dies in his sleep, and Michelle falls off a horse and get hurts her head really bad, but nothing violent. (you don't see any blood when Michelle hurts herself).
I have only heard h**l, but common sense says there is also da**, but I don't think it is a big issue.
There are usually 2 problems in 1 show, but it always comes to an end (except if it is split in two parts).
