I like them either way...in Reign of Fire they made awesome villians, in Dragonheart they made awesome good guys (well more like guy).
It all depends on the telling of the story, in acient legends, dragons where always fierce bastards, who didn´t treat humans as the god given sacred race they like to be treated as (and no human likes NOT being treated that way) so they seek out to destroy said dragon.
If you try to get more into it, the dragons point of view could be very interestingly told, and maybe become a tragic tale of a missunderstood creature and so on and so forth.
What i really loathe are these artistic "what if" point of views. They could be considered the "neutral" aspect.
I remember one BBC documentation about Dragons ending with an awesome cliffhanger.
And yes, it WAS a documentation. They pulled it off quite nicely.
The general Plot was some geologists find the sceleton of a winged creature that is unknown to them, so they call in some investigators, and soon the theme of dragons is pulled up.
Everyone is like "NO WAI!" and then try to disprove this sceleton to belong to a dragon.
They come up with quite alot of reasons...it couldn´t possibly fly, it was too weak for it´s wings to carry, the wings where weak and looked like they couldn´t work for shite, the Bonestructure was weak.
Then they found out it was a female dragon but don´t find any resonable level of hormones in the remains that should have been there if it went through puberty.
Then they go back to the place it was found and find a second, way larger sceleton and come up with the idea that what they found was mearly a youngster.
Then they find human sceletons in medival armor and the tip of a spear in the larger sceleton, and "reconstruct" what might have happened in that cave in the 11th century.
It also brought up nice theories about why western dragons look so unequal to eastern ones and how they could breath fire (No magic, their explaination was that dragons could have used gasses generated by digesting and local stones on their teeth to ignite a firestream. They would bite on the stonepowder left on their teeth to generate a spark, which would ignite the gasses, quite interessting) and such.
