In general. First Act is full of hopes and uncertainty and the great suspense in knowing that everything is about to change forever. Second Act puts everything on end, foils the plans, crushes the hopes... For a moment it may even make you regret going on the journey. But then things turn, the sky clears and you come to discover a truth and a stronger hope, and they lead you to: Third Act. Yawn. Everything seems simple, all of the sudden. There's only the final showdown left, and we all know how that's gonna end. So third act is stuffed with high-speed action in order to keep the audience from dosing off. But I'm really just waiting for THE END. This is how I end up feeling when I watch many movies and read many books. Except for those that totally violate classic progression of fiction. I'm trying to break out of this, with my own story, but it's hard. It's engrained, somehow, and inevitable, that at some point sooner or later, all the questions have to be answered and the ending must seem naturally ahead. I just think its boring. Even the greatest of adventures momentarily lose me at this point. The car-chase part serves best for a toilet-break. Even 'Return of the King' put me to sleep with all those endless battles. Do you feel the same? Or do you actually think the third act of, say, Indiana Jones is the most interesting part of the movie? Just taking a well-known example here. Feel free to substitute it.
