I have always enjoyed action movies; the more gory the mindless violence the better. Explosive stuff aplenty? I'll be there with bells on. You never really think about the gun stances that the actors take and I'll bet a lot of people thought those things can and really do happen.
Chuck Dixon very kindly disabused me of those notions in his post here. Now the next time I watch something with gratuitous gun violence, all these details will pop into my head and take me out of the story.
