True, Ron Howard is a big exception to that. Plus, there are doubtless many other kids who went on to careers in other professions who we just don't know about. I think Winona Ryder could have had a continually successful career but her own issues stopped that. However, I also think that, just like a year or so ago there were articles about how Jennifer Lawrence was overexposed, I think that Ryder suffered from that too, which is why there was more of a backlash against her.
