Don't get me started on Hollywood. (Actually, you did.)
One of my biggest gripes is the use of sound effect of 9mm brass hitting a concrete floor. Tinkle, tinkle, tinkle... They use it all the time, even when it's totally off the wall.
I remember when I had time to go to the movies. I was watching "Patriot Games", and after one bad guy shot the other, you could hear the tinkling of 7.62 (9mm) brass bouncing around on the sand. That took me so much by surprise that I blurted out "GMAFB", and was told to keep my opinions to myself.
Other gripes include the "click, click" sound of hundreds of safeties being removed (deafening, if it was AK47s), as opposed to the "old days" of everybody thumbing back the hammers of their SA and DA revolvers to show that they really meant business.
And what is probably a 100-year-old tradition in Hollywood, the "figure 8" view through binoculars. I think I only saw one movie where they got that right.
On the upside, this is what the left uses for weapons training.
