I think they should have gotten more reconition. Besides Smaug and in the First Age. I mean I think Peter Jackson sould make a movie about the First Age and the fall of Numenor. So ya they should have mentioned them more!
The only thing i remember is in the fellow ship of the rings were Gandalf lights a dragon firework. And Frodo says Bilbo watch out for the dragon and Bilbo says nonesens there has not been a dragon in these parts for 1000 years.
they should have bred more of the fell beasts that the nazgul use then give one to the mouth of souron and give some to some to the orcs to form a sky calvary battalion
