It is really very funny and a philosophy movie. This movie also good story you must watch.
Aamir Khan excels in the title role. his Bhojpuri accent and his love for’paan’ only adds layers to the character of PK. Anushka Sharma, who has in her previous releases earned quite a bit of critical acclaim, does a good job as Jagat "Jaggu" Janani. She stands shoulder to shoulder with Aamir through the entire film. Sushant Singh Rajput is impressive in an extended cameo. Saurabh Shukla, though good, seems to be underutilized along with Boman Irani who too could have been given a meatier part. Sanjay Dutt, on the other hand, manages to carry off his role as a Rajasthani man with panache. It takes the ‘stranded alien’ theme, familiar from classics like ET, but tells the tale equally from the lonely alien’s eyes – at times, evoking the beautiful story The Little Prince – as from his human narrator’s. Starting with the alien’s desperation, PK captures the fears and falsehoods humans weave around faith. When PK decides to pray for his remote, he’s bewildered about whom to and how to pray. PK features brave scenes – money extracted at temples, coconuts offered in confusion at a church, god-men doling out tortuous advice – and strong lines, including a Muslim girl bravely asserting, Capturing faith whipped into hate, PK’s sterling message, directed sensitively. so friend please see.
