I just ignore most of it but I have to say watching sparks fly for something that is shot, plastic, wood, glass, aluminum, whatever brings a smile to my face. Another is anytime a lever action rifle is used, no matter how many shots have been fired from it, when it gets down to the nitty gritty and the good guy has the drop on the bad one they always cycle the lever. To top it off no empty case ejects. I saw a recent western where the gal with the rifle caught the baddy and actually just cocked the hammer which surprised me. However if my life were in danger and I was sneaking up on the villian the rifle would be cocked and ready to go. Another is holding a hammer fired semi-auto on someone and when they don't answer your question the gun holder cocks the hammer. I suppose that is supposed to indicate that they are serious. Another in westerns is being chased to a spot where you abandon your horse, leave your rifle in it's scabbard, and duel it out with a sixgun at extended ranges.
I just watch mostly for the story line and let the silly things go except when I am watching with my oldest grandson and I point them out just to get a rise out of him. His reply has become, "It's a movie, granpa".
When it comes to news most reporters, print or TV, know about as much about guns as my last weenie dog did.
