The "snow" got me too.
Dragon riders.
Watching the scenes of dragon riding instantly made me wish for the hundreth time that Ann McCaffrey's dragon series could be brought to the big screen.
Haven't read them in 30 years but the images she painted are still in my head.
Her treatment of time travel was delightful and like on Pandora, bonding with your dragon can be deadly.
And I wouldn't mind getting a visual of Lessa of Pern...
