Heavy Rain?

I saw an advert for a game called 'Heavy Rain'...To be honest, I wondered what the smeg that was all about. It made no sense, neither did the adverts for it. I can only describe it as a film-like-game.
Wikipedia said... "The player interacts with the game by performing actions highlighted on screen related to motions on the controller, and in some cases, performing a series of quick time events during fast-paced action sequences..."
Is it me, or does that sound like every game? I'm confused by this...Very confused.
