“Malls R Us” is a new documentary about malls. And it's not what you think. It's not a film that bemoans America's mall culture. It sounds like it's a bit conflicted. Some of it sounds like it celebrates malls and the role they play as gathering places. Some of thegoes so far as to call malls “holy places.” There's bound to be some criticism as well-perhaps looking at the effect malls have had on the development of America's downtowns.
