It is implied here that Wes created all the Nightmare-movies. That is incorrect.  Wes wrote and directed the first Nightmare from 1984, co-wrote and produced Nightmare 3 from 1987 and wrote, produced and directed New Nightmare from 1994.  Those also happen to be the most memorable and interesting movies of the entire franchise.   Rest in Peace, Wes.  At last Freddy is back where he belongs...
