After very careful and lengthy analysis, I might have to concede that TPM is a slightly better movie than the Holiday Special. However, to the original question, midichlorians vs. Life Day... that's not easy. Life Day is vomit inducing, whereas midichlorians are icepick-inducing.
Another related question... what's worse, "Jedi Rocks" or "Ode to Life Day"? That's not easy either.
