3. Parsnip Of Power
Plot: Dwayne Johnson stars as Farmer Bob in this heart-warming family film about a man trying to grow the world's biggest parsnip. Despite sacrificing time with his family to tend to the titanic tuber, Bob eventually convinces his wife and daughter to help him haul the vast vegetable out of the ground in order to enter it into the village fête. But what's this? It's that blasted Man In The Sun again, only this time played by Will Ferrell because of the previous disagreement with Adam Sandler! What will the solar slimeball get up to this time?
Reason abandoned: It's about a frickin' parsnip.
4. Mr. Mingy's Thingy
Plot: Johnson is Mike Mingy, a normal, down-to-earth, massively-ripped guy who lives with his wife, three kids and, uh, dingo in rural Wyoming. One day he discovers a yellow, dome-shaped object with strange red markings in his yard, and the phenomenon becomes known as Mr. Mingy's Thingy. Scientists from all over the world come to investigate in the hope that Mr. Mingy's Thingy is a sign of extraterrestrial life, but it eventually transpires that it's just a big mushroom. Mr. Mingy cooks it for his family, and everyone lives happily ever after.
Reason abandoned: Potential encouragement of drug use among minors.
5. Journey To The Centre Of The Erf
Plot: Dwayne Johnson stars as Dr. Pierce Jones, a specialist in the field of vulcanology. When his daughter Ayesha paints a top-down view of a volcano he's never seen before, he whisks his family away to locate the mysterious mountain. After years of searching and various improbable adventures, the volcano in question is found, and it appears to provide a gateway to another planet: Erf. The inhabitants of Erf prove to be selfish, arrogant and self-destructive, and in a final twist it's revealed that Dr. Jones and his family were, in fact, on Earth all along. Nobody is surprised.
Reason abandoned: It's just complete rubbish.
