Oh lots.
Basically that group of people prefer things to be real rather than made up fantasy. I tend to see it far more with older rather than younger generations, but its not exclusive to the older generations. Heck don't forget there was a time when fantasy was considered very abnormal - I seem to recall the writer of Guiliver's Travels getting into trouble for publishing a book which was untrue.
Some also consider it a childish thing, which is often promoted by the fact that many fantasy stories and sci-fi are often pitched toward the younger generations in marketing. So they don't want to take part in it because they consider themselves adult and thus not childish any more. CS Lewis has his famous quote “When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.” Which is adapted from the Bible quote "When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me."
I would wager to most Chrons members CS Lewis sums it up for them, whilst for those who are more "real" its either an untrue statement or a way of thinking that they've not entertained.
And yes James Bond or other "real" or contemporary dramas or films are "allowed" because whilst they include many sci-fi elements; they are grounded in enough of the real world that the sci-fi can "make sense" (even if in reality it doesn't). It's why shows like NCIS and such work because even though most of them abuse the science to an insane level; most people wathcing don't know science to even a basic level to know where the make up and reality lines are drawn (some areas are obvious, others are very hard to work out and some of the most insane ideas often turn out to be more true than not).
And, of course, the older many people become the more entrenched their views become. Especially if their life is not presenting them with continual challenges against those world views. If they've no desire to push or change their own views then they won't engage with the material that will challenge them, thus those views they already have become stronger and stronger.
It's not to say they never can change, but that it would likely take a lot of outside influence and the right exposure to the right material to change their views.
Edit - also don't forget many people live lives where their job is very much their life. It fills most of their waking moments in the world so they've little to no desire nor time to really devote toward something that isn't related to life or their work. Sure they'll take an interesting real world things like politics and such, but they've really not got the time nor inclination nor benefit (in their view) of "wasting time" daydreaming or reading fantasy. Heck many might not read many novels, if any, at all. It's just not a passtime for them; whilst their TV choices might be more just for the noise than the content (There's many a person who turns on the TV just to have a background noise - just like the radio)
