3. PK

IMDB LogoIMDB Star
8.2/10
Rotten Tomatoes Logo76%
Reelgood Logo
87/100
Released: 2014Rated: PG-13
Comedy, Drama

What it's about: This experimental satire is a comedy of ideas about an alien in the city, who asks questions that no one has asked before. They are innocent, child-like questions, but they bring about catastrophic answers. People who are set in their ways for generations, are forced to reappraise their world when they see it from PK's innocent eyes. In the process PK makes loyal friends and powerful foes, mends broken lives and angers the establishment. PK's childlike curiosity transforms into a spiritual odyssey for him and millions of others. This offbeat, experimental drama is an ambitious and uniquely original exploration of complex philosophies. It is also a simple and humane tale of love, laughter and letting-go. Finally, it is a moving saga about a friendship between strangers from worlds apart.

Where to Watch: Available to stream on a popular subscription service (Netflix).
