Pleasantville/Fridge

Fridge Horror

 * On Pleasantville, the two protagonists are Trapped in TV Land and teach the citizens of TV Land to be more real, implying that everyone in the eponymous town was a real person who just needed to be "fleshed out", so to speak. But to do so, they take the place of Bud and Mary Sue, the children from the TV Show. Mary Sue is literally Put on a Bus to a college that showed up when the world became, well, realized. But this doesn't solve the problem with Bud, since David went back to the real world... and even worse, it creates a new Fridge Horror: Jennifer/Mary Sue never returned to the real world. Surely someone would have noticed at some point?
 * I just assumed that the real Bud and Mary Sue were in the real world, and learned the same lessons from the other end.

Fridge Logic

 * Wow the mom is in color now! Great huh? Until you realize gaining color is usually associated with sex, her husband was still black and white
 * Gaining color was associated with Character Development. The husband gained color when he felt real love for the first time. With regards to sex, the mom said her husband "would never do that kind of thing" for her, meaning he is oblivious of sex as much as she was. Hence the bathtub scene and the tree bursting into flames.
 * A rare in-universe example, all over the place with the show. Highlighted once they enter the show's world where the things never addressed in the show simply don't exist. There are no toilets, there's literally nothing outside of Pleasantville, and the residents don't even know what sex is. And of course, the entire world is actually monochromatic.
 * Out of universe: If there's nothing outside Pleasantville, where did the opposing basketball team come from? At the very least, without any roads leading out, how did they get in?
 * They're cross-town rivals.
 * Another explanation: they get in off-screen. The citizens know about the USA, they just don't need to go there.
