This article seems to make the question of realism a universal either-or proposition, and I don't quite agree with that stance. In my opinion, context, intent, and premise are key factors in determining the fantasy to reality ratio that is acceptable. There are movies(typically any fantasy film) for which it is so obvious that reality must be thrown away that I have no expectations whatsoever regarding any realism. My only requirement in such a case is that the film establish a self-consistent fantasy reality and not violate that fantasy, i.e. don't make your own rules and then break them.
But, then there are other films for which reality must be front-and-center and not deviated. One may have situations with extremely low probability of occurrence or even seemingly improbable events(for example, a movie about someone who actually does find that their body has quantum tunneled to the other side of the galaxy); however, these are not necessarily violations of reality as they simply require more knowledge and calculation of the statistical flexibility of the universe to see that such events can, indeed, occur. In fact, with a little digging into some of the deeper areas of quantum mechanics, statistical physics, and relativity, one can find all kinds of weird things that do actually happen, but for the lay-person, many such things would seem unrealistic only because they lack the knowledge and experience of such things(i.e. it's something that's non-intuitive). Also, remember, in many ways, today's science is yesterday's magic. This would not just apply to sci-fi, fantasy, and action films; it could apply to other film genres.
In my opinion, to really be able to meld known reality with notions of fantasy really requires a broad knowledge-base and keen understanding of concepts. This may be where film-makers are failing; they just don't understand enough themselves to create a convincing conjecture of possibilities spawning from our current reality. As a result, a more knowledgeable audience has difficulty suspending disbelief, and this may be from where some of Movie Bob's quandary is coming. (Of course, I admit, I could just be totally off-base on this prospect.)
For games, I'm generally more strict about not wanting reality shoved in all the time as a means of making a game "good" or "immersive". My position with games is usually if I want reality, I wake-up in the morning, not pay some game developer $50-60 to make a failed attempt at recreating it. However, this is because my own personal intent with games is purely to escape this reality for a time and try some other reality. For purposes of immersion, I only require that the game establish a self-consistent set of rules and not violate those rules.
