Slow Transformation/Playing With

Basic Trope: A really, really slow transformation.
 * Straight: John is bitten by a zombie, but it takes a whole week for him to completely turn into a zombie.
 * Exaggerated: John only finishes his transformation a whole year after he is bitten by a Zombie.
 * Downplayed: John finishes the transformation within twenty-four hours, screaming in agony the whole time.
 * Justified: John was only infected with a sinlge particle of The Virus.
 * Inverted: John is bitten by a zombie and immediately becomes one himself.
 * Subverted: John seems to be taking a long time to transform, but is then bitten by another zombie and proceeds to transform twice as fast.
 * Double Subverted: ...only to have Alice inject him with the last of the anti-virus, which isn't enough to eradicate the virus but at least slows the transformation sequence enough to possibly find more anti-virus.
 * Parodied: A side screen shows a panel of grass growing faster than John's transformation.
 * Title Card: "...Fifteen years later, John was a zombie."
 * Averted: The transformation is finished in a matter of minutes.
 * Transformation is not a plot point.
 * Lampshaded: "Geez, when will it all be over?"
