Why can't Hollywood get fireworks correct in movies?

Specifically the timing of the sound....Do they really think we are that stupid or forgetful? Or have they never been to a fireworks show?

  

Anyone who has been to a large 4th of July or new-year's fireworks display knows that the sound comes a full second or so after the shell burst. But even in a relatively new movie that I saw today (Adventureland) The sound is heard at the EXACT same time as the burst.

  

This is very distracting to an engineer.  The first time an engineer sees a professional fireworks display, that delay in the sound is a real wonder, and adds to the magic of seeing a display. You see the big burst and your mind knows the boom is coming in a split second. The anticipation is part of the joy.....But Hollywood sound editors kill that joy. (maybe it's not the editor's fault, but I suspect it is)

  

Seriously Hollywood...get your act together.

  

Is there anyone who can list a movie with a fireworks display with a correctly timed soundtrack? I don't remember one.
