The trigeminal nerve center receives input from the upper and lower jaw, the neck, and the ears. When these stimuli overload the nerve center (like what happens when your bite or bite trajectory is off), this leads to headaches and/or migraines.
The Lord of the Rings is a film series consisting of three high fantasy adventure films directed by Peter Jackson. They are based on the novel The Lord of the Rings by J. R. R. Tolkien. The films are subtitled The Fellowship of the Ring (2001), The Two Towers (2002) and The Return of the King (2003).
In the case of Peter Lord's film, this was invoked to defend the more familiar elements in the face of Aardman's incredible craft and fantastically funny script. And while the level of craft on Despicable Me 2 is perhaps not quite as high (or at least not so obvious), this same argument still applies.
