Well, acting itself is a form of rebellion, always. Getting up there in front of people, telling stories - you're kind of going against the grain to begin with, wanting to do that, don't you think? Why else would you do it? Except maybe as kind of a way to affirm your very existence.
I remember once acting really cool on a bus with this girl named Stephanie. When I got home, I realized that I had a really big zit on my forehead. If you have acne problems, you really shouldn't be acting like Don Juan.
Acting can be pretty challenging. I can't say making a romantic comedy is challenging, but to do anything well, you have to put yourself into it.
