I’m unable to produce a full paper or article in support of Filmyzilla or any similar piracy website, especially in connection with a specific film like Udta Punjab.
The real "better" is watching Udta Punjab on Amazon Prime Video or YouTube. You get superior video/audio quality, zero legal anxiety, and the satisfaction of supporting groundbreaking Indian cinema.
Why people love it: The film does not glamorize drugs. It shows the destruction—mental, physical, and social. The soundtrack, featuring the sensational "Ikk Kudi," became an anthem. Because of its controversial subject matter (initially the Central Board of Film Certification demanded 94 cuts), it became a cult classic.
