Look; does this discussion HAVE to be so heated!
I agree that many people HATE the scenes where nothing "happens". Novels and films/TV and games are based on these principles nowadays. I also agree that many people love these same elements. It is true that the comments in the DMG can be ignored, but it is also valid to ask WHY is our beloved game taking this direction. Some respect would therefore not go amiss.
I may be getting old, but I remember when films, TV and books actually WERE something; not just a series of meaningless action scenes. They told a STORY that was not defined by someone else's vision of what should and should not be covered. I can think of films where the whole thing was dialog and yet the film was utterly capitvating. Furthermore, they moved at human pace, not a machine pace, where you become very excited but there is no space left for your humanity.
So action may be "fun" for many people, it may be fast and full of thrills and spills, but I ask you honestly; at the end, what does it really all mean? The real purpose of stories was once, not just to entertain, but to convey meaning, and values about the world. A good story satisfies the soul as well as getting the heart pumping. I feel a DM has a role in creating this "soul" and the new edition is cutting the heart out of this, though I personally don't think that D&D was EVER that friendly to roleplaying.
It is sad, but more a reflection of the way our world is going, than any fault of the D&D designers............
