Because there's no such thing as "Game Over" in Heavy Rain, everything you do will have an impact on the branching storyline. Here's an example of a gameplay scenario where the player is faced with a certain series of tasks and decisions; you might do things differently. And if you do, that will certainly alter how the plot advances. This is perhaps the most ingenious part of Quantic Dream's innovative adventure game: rather than follow all the traditional paths, we get a unique, emotional, and downright thrilling experience. Yes, it's about more than just QTEs, provided you can appreciate artistic content.
