It lost all credibility in the last half hour. Those were the crappiest dragon slayers EVER! HAving seen Dragon Storm, I know Rex Manning is the only competent Carpathian dragon slayer!
I learned that if it weren't for dragons, man would never have fire. (Prometheus was eviserated daily for nothing!)
The show failed to explain why dragons would be extinct if they're so well suited to so many environments and situations. Surely they'd be flourishing in China!
The water dragon that became a Chinese dragon should've had catfish whiskers.
Why couldn't the Carpathian dragons just survive on villagers?
The didn't need to make fake stained glass panels of dragons with all the real dragon folk art that exists.
I would've liked to see more of an intersection of biology and myth, perhaps explaining the Alaskan dragons they kept mentioning that I've never heard of.
