"Not that anything could be heard above the roar filling out the San Diego Convention Center. It was there, mostly in the fabled Hall H outside of which attendees line up overnight..."

Means next to nothing, today. What, 10-15,000 maybe?  At stake here are audiences of MILLIONS.  Next: 

"Warner Bros. detailed plans for nine DC films..."  If that is all these films are (just "detailed plans"), it's easy to put them in the wastebasket. A film in re-shoots is a different thing (and possibly a disastrous one)--too late to shelve it, now!

Wouldn't be the first time that "Hollywood" (or whatever it is in the international film era) got caught flat-footed by fickle audiences.  Remember cinema?  Three-D (dormant for 40 years after the first exploitation flicks).  Gosh, who recalls Sensurround? Two films (Earthquake, Midway) and then gone and forgotten.  Film content: blackexploitation flicks, motorcycle flicks, exorcist clones...first (and MAYBE) second editions got the bucks.  The others?
