A ‘great’ post here although not one for the squeamish.

However, I highly recommend it as it is very informative and, I suspect, accurate.  It is also a little amusing in places, for instance, this bit:

…..after any on-screen death, the deceased is looking as clean and sanitised as a made-up corpse in a funeral home. They do not poo in their pants of fill their mouths with Kraft-Cheesey-Pasta-Esque strings of phlegm.

They definitely don’t leave one eye steadfastly stuck open no matter how many times you demurely pass your hands over their face, leaving you with the dilemma of “I wish I could close that lid, it looks bad, but the only way to do it is to poke this dead man in the eye…I’m pretty certain I’m not supposed to do that.”
