One of the most uncomfortable facts of life when it comes to celebrity culture is that the more we want to know about a famous person, the more likely we are to see them when they're struggling the hardest.
When those struggles take place over a protracted period, it's hard not to feel voyeuristic with every update on their behaviors. It's also true that while the general public often seems to have a long memory for a given's celebrity's misdeeds, only their fans seem to follow-up on how they grow and address those past behaviors after the fact.
Still, one could also argue that this context makes it all the more exciting when the people we're watching overcome their demons and all the more encouraging when they're able to stay the course for years or even decades after the fact.
