Pretty much Perfect!
Some folks might complain about some of the animation (I get that, it was certainly not Pixar quality) and I honestly don't know what that silly closing credits song had to do with anything, seemed like a crybaby guy whining about something??
But overall, the voice talent was terrific, the plot of the novel was accurately adhered to and all of the important themes were present (death, loyalty, courage, love, friendship, fear...)
The BBC and Netflix nailed this one
Love this novel and really respect this adaptation
Well Done!!
