The 2013 Bollywood hit "Grand Masti," directed by Indra Kumar, marked the second installment in the popular "Masti" franchise, following the success of the original 2004 film. Starring Vivek Oberoi, Aftab Shivdasani, and Riteish Deshmukh, the film became a superhit, known for its bold and risqué humor. However, despite its commercial success with a worldwide box office collection of around 145 crores against a 35 crore budget, "Grand Masti" is firmly an adult comedy packed with explicit jokes and situations that are unsuitable for family viewing.

The film features a storyline about three married friends seeking fun during a college reunion, but it is laden with adult-themed content, including sexual innuendos, suggestive dialogues, and scenes showing cleavage and semi-nudity. The humor is often vulgar, involving double entendre and adult jokes that may make many viewers uncomfortable if watched with family members. Though it does not depict explicit sexual activity, the strong emphasis on sexualized content and references places it clearly in the adult category.

Critically, "Grand Masti" received mixed to negative reviews mainly due to its extreme sexual content, poor script, and reliance on low-brow humor. While youngsters and fans of adult comedy embraced it, family audiences largely rejected the film. The movie is rated 'A' (adults only) and is best enjoyed in private settings such as with friends or a partner, rather than with family.

If interested, viewers can find "Grand Masti" available on OTT platform Zee5. Its popularity over the years has even encouraged a fourth installment, continuing Indra Kumar's legacy of adult comedies under the Masti franchise.

In summary, while "Grand Masti" is a successful Bollywood adult comedy classic filled with laughs for mature audiences, it absolutely is not suitable for family viewing due to its explicit humor and adult themes.
