Isn't it funny when we are in the midst of reading something, and we see examples of things we read in real life?
I'm currently reading Robert McKee's Story (excellent book for any writer). He mentions the inciting incident - that thing which sets the action, emotions, and plot in motion - needs to be carefully timed. Do it too soon, and the audience is confused or not bonded to the characters. Do it too late, and the audience is bored.
The recently released movie Shoot Em Up is a perfect example of the inciting incident which occured too soon. The first fifteen minutes of the movie had action-packed adventure, incidents, and flashy stunts--but I wasn't invested in the characters (other than liking Clive Owen as an actor and realizing he was trying to stop some bad guys). The movie waited until the second hour to offer the explanation WHY he was having to chase the bad guys (and even then, the reasoning wasn't a great premise).
However, inciting incident timing aside - sometimes great stunts do have their place. And Shoot Em Up had some INCREDIBLE stunts.
