Americans Hate Tingle: The series has gotten less than favorable reviews on Crunchyroll, though this is likely because of its kid-oriented nature on a platform mainly aimed at teens and adults.
Arc Fatigue: Many viewers have spent 12 episodes waiting with Calen in order to see who the person she's waiting for is, but every episode just dodges the question until the very last second, and she never gives the audience any more information about them that might make the looking process easier. On episode 16, it's implied that he doesn't even exist and might just be a figment of Calen's imagination.
Heartwarming Moments: The Christmas Episode, which didn't require a True History for once. Santa suddenly falls ill, and Calen and Tokio send presents to children around the world, with Santa delivering the last present. And for once, the Akudarma trio get a well-deserved feast.
