Awee H2O, that's so sweet. It got me too, though I can probably watch it again. Heck, I was still living at home when I watched it, and my mom came to tell me something like, do this or that or something and it was NOT a good time. LMAO.
Anyways, if you're talking about 'haven't we seen this story before?' then you can argue dat shit for about 90% of the movies.
But yes, there are some originals out there once in a while. Hurt Locker was nice - a war movie, but with a different focus.
The Book of Eli was nice as well, I thought. Very original.
