The first few hours in Twilight Princess are probably the worst in any Zelda game that's been released. I was losing interest as well but decided to persevere. It takes a lot of things that made OoT great and improved on them in many ways.
Ocarina of Time was too ground-breaking to be surpassed for me but TP was not far behind. You should definitely play through it at least once, Vivi. You won't regret it!
