Not an exaggeration. It's really that charming! Terry Pratchett's gentle humor, the instantly lovable characters, the adorable animation and memorable score really elevate this one far above other Christmas shorts.
And unlike most of the animated British classics shown around this time of year, it has the added benefit of remaining a happy and heartwarming story throughout, making it perfect comfort viewing for children and adults alike.
Even at nearly 40, I find myself fully immersed in the story and am looking forward to re-watching it as an annual Christmas tradition.
Really, the world is bleak enough as it is. We all need more Pratchett in our lives!
