The parental burden
One of the duties of a parent is having to sit through 'must see' movies on a Saturday afternoon, the worst of which in my case being, by a considerable length of chalk, Pokémon: The Movie 2000. I would honestly rather undergo dentistry than have to sit through the final hour of that for a second time.
G-Force wasn't much better but was mitigated by being presented in 3-d (so you could at least nod off behind the dark glasses without too many people noticing).
