I think that almost all of the stuff mentioned in this thread can (and sometimes does) work in the right context. Like, I don't have problems with us getting a flashback where Ma or Pa teach Clark some important lesson. Problem for me becomes when this is all we get with them. You know, maybe sometimes we should get some stories where they are average parents and don't teach much, or make completely stupid decisions that end up hurting Clark. But nah, they are perfect.
