Yes, these three men above me, foont, oyvoyvoyv, and BrainBoxLtd, have basically summed it up.
Any plot can be reduced to something as simple as Zelda's. Even something really up its own ass like FF7 can be boiled down to "save the world from the big bad who would destroy it".
The story is different. Twilight Princess is about more than stopping Zant - I think more of the story would be in how the Zora queen dies, and how this affects the people around her (especially her son), and various other touches that you carry with you.
