The worst film ever made, written directed by lame arse director M. Night Shaylaman. The idea isn't that bad but the ending explained nothing and looked as if it had been finished in 10 minutes in the pub on the last day of filming.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

A waste of money and your life.

Mark Wahlberg's biggest mistake.

1. A synonym for a plot twist or turn in a story (eg, book, movie) that is extremely convoluted and anti-climactic that makes something that originally had good potential seem completely pointless.

2. The film of the same name by M. Night Shymalan (he used to make kickass movies like Signs and the Sixth Sense) that birthed this definition. It starts with people mysteriously killing themselves like under a trance, but the twist is that plants are giving off toxens that are causing humans to do it. An unintentional comedy.
