In addition to being a great film, 12th Fail is a significant one. I will never forget this film, which I will watch numerous times, even though it made me cry. 
Regarding the film's production, the performance of Medha Shankar, Anant Vijay Joshi, Anshuman Pushkar, and the relatively young Vikrant Massey is superb; it feels genuine and accessible. Every character has been given adequate development, and their interactions are genuine. Based on IPS Manoj Kumar Sharma's true narrative, the film presents every scene as though it actually happened. The lighting and colors in the filming are exquisite, giving each scene a sense of depth. Shantanu Moitra's music is spot-on, particularly the emotive and evocative background score.

The film makes excellent use of both sound and stillness, which enhances the narrative. The language is excellent as well, finding the ideal harmony between subtle comedy, muted emotions, and sentimentality without becoming overly emotional. It is difficult to criticize any part of 12th Fail's filmmaking. Perhaps Vidhu Vinod Chopra's best film to date is 12th Fail, despite his career being full of amazing films like Khamosh, Parinda, 1942: A Love Story, Munnabhai MBBS, Parineeta, and 3 Idiots.
The message of 12th Fail is what makes it an all-time classic rather than just a good film. Through the story of one man, Manoj Kumar Sharma, who goes from cheating in school in a village in Chambal to pursuing his dream of becoming an IPS officer among the coaching centers of Delhi, 12th Fail depicts the struggles that the millions of IAS and IPS aspirants in India face every year.

The movie depicts Manoj's (Anant Vijay Joshi) unwavering optimism in the face of the most tragic struggles with great poignancy. It contrasts well with the personal demons of Pritam Pandey (Anant Vijay Joshi), the relative privilege of Shraddha Joshi (Medha Shankar), and the unwavering support of Gaurinandan (Anshuman Pushkar), his mentor. The film conveys a few positive lessons, such as how the community benefits when one individual succeeds in becoming an IAS or IPS official, the importance of never giving up (Haar Nahi Manunga), and—above all—the film's central theme of rising from failure and trying again. RESTART.

This movie is the ideal illustration of how to take a factual tale and turn it into a powerful, inspirational film. It shows the people who are pursuing the civil services test (UPSC) in order to enter IAS or IPS with a never-say-die mentality and tenacity. 
This will surely inspire many and will give morale boost to many aspirants and will give it's viewer to think after watch.
