Answer:
I think that Hellen Keller was a very loud and outspoken person for someone her age and with her conditions. My thought about this is that it is what she uses to try and comunicate with other people to make sure that they would still notice her.
It can change a lot of stuff, including a persons entire view of the story. Imagine if the harry potter movies or something like that came out in a different order. Probably would be a lot different now.
Hmm. A bit tricky. This going to be a phony choice, but if you wouldn't mind it, then I would say the "Bratz" movie. It's 10 years old, and was panned by a lot of people, but it still has a pretty good plot like making friends and things that happen in school. Or maybe "Princess Protection Program", which also has a good plot of friendship and what not. I know it's odd and sounds chessy, but if you think about it, they can teach some lessons about life, plus it's appropriate for students to watch.
