Monsterquest sends an expedition team into a remote mountainous tropical rain forest on a large island in Papua New Guinea. Their stated purpose, to search for a large nocturnal flying creature reported by eyewitnesses, is fascinating and worthy of the effort; but the pre-production assumptions of the Monsterquest producers ensures that the possibility that a pterosaur species still lives---that possibility is not given proper consideration.
Don't misunderstand the low rating I give for this episode (4 out of 10). I was fascinated by much of it, and the production values are high. Important eyewitnesses and cryptozoologists are shown and given reasonable time and opportunity to speak, in general. Many viewers should really enjoy it.
But the overall philosophy of Monsterquest allowed crude skepticism to go unanswered, when powerful answers could easily have been included. Dogmatic traditions were given far too much emphasis. With that said, I believe this episode helped many viewers to become aware of a phenomenon that they had never before considered: Modern pterosaurs may still live in our wonderful world, at least according to eyewitnesses.
Watch it, but remember to consider the possibility that the eyewitnesses were telling the truth and accurately reporting their encounters. Don't get fooled by dogmatic assumptions about extinctions.
