qte's are also painful to develop - you need believable states to be in when it occurs, and you need good fail/success scenes, it splits up everything and cutscenes would be better without them - or maybe we could make video games that aren't movies and have the action not so frenetically cut between dozens of cameras that you can have the player take part in the action.
there's a few games that do this well - i think uncharted has got some great ideas hidden behind some less great ones. the chase sequences actively involve the player. remember the scene from uncharted 2 when you were being chased down that street by the truck, and you had to shoot at it - and then it crashed and exploded? that would have been a cutscene in a hundred other games. the fact that it's a polished mechanic is what raises that game above games where it's just a cutscene.
call of duty 4, the post-nuclear bomb section, beautiful piece of the game, completely the moment that made it my GOTY - could have been a cutscene, artfully directed by some amateur wannabe director in the cg department, the fact that it was made into gameplay using existing mechanics of the game is a perfect example of how to do it.
then the closing of that same game, where you are thrown a weapon and have to make the shot. that was utterly beautiful, a perfect note to end on, and could so easily have been a cutscene.
the fact that these games are high scorers and games like heavy rain aren't (HR got pity scores, it was a turd and you know it) is precisely because the player is involved in the highpoints of the story. they are given, in their eyes, the opportunity to make their own destiny. the fact that they care enough about the characters and the events that they will do precisely what the designer asks of them at a specific moment is another area of skill altogether.
tl;dr if you're going to have some section of a game that can't be played with the regular mechanics the make it into a new mechanic and make it work.
games liek metal gear are an exception to this, they have such completely movie-like cutscenes that QTEs simply aren't feasible, and the action is portrayed in such a way as to be enjoyable to watch, so you don't feel too frustrated that you aren't taking part. although MGS4 really pushed it and it was one of the biggest complaints.
