Gremlins: Secrets of the Mogwai Finally Reveals Gizmo's Origin Story
Gremlins: Secrets of the Mogwai finally reveals the heartbreaking truth behind Gizmo's origin and it proves why humanity never deserved him.

In Gremlins, the protagonist's father brings home an adorable new pet he found in China, which he calls Gizmo. The alien species is referred to as the Mogwai, and before coming to Earth, the creatures were created on a distant planet to bring peace to nearby civilizations. However, this species is unstable as they produce rapidly and undergo metamorphosis before transforming into little green troublemakers.

Gremlins came out in 1984 and originally had a rating of 15, which was lowered to PG-13 months after its release. These days, children are exposed to so much more, so this comedy/horror movie seems pretty tame compared to today's standards. However, the dated classic is considered by many critics to be one of the most iconic movies from the 1980s. Many people who were children at the time still speak highly of Gremlins.
