Oh yes, I've read about this - I'm sceptical about its validity and although there is some evidence to support it, it's not conclusive. I'm a little against general psychology (I think it's a pseudoscience) and, although biopsychology (behavioural neuroscience) is something I
do believe in (flight or fight, for example). So I don't think I'll be taking part.
But I can still answer the question....
I think all spy movies need a combination of the three options, but it's down to personal preference and what people like in a film. I personally enjoy the Spying (Covert) action of spy films (and I like games like that also, such as the
Metal Gear Solid series).
So...
