1. Performances: The three main actors gave excellent performances.Mammotty stands out above the rest on screen thanks to her unique screen presence.The opening scene serves as an illustration.The character's shade is available right there. His delivery of the dialogue is excellent.It is impossible to overlook the nuanced shift between devilishness and pity in the last moment.Siddhartha Rathod is a revelation.It's unbelievable how much this man has changed from his mediocre performance in his first movie, Nammal, to this level.Genes are genes, of course, and they worked out nicely in this case.The key quality of Arjun Ashokan that I found appealing was his ability to really inhabit the role.His body language made it obvious that he belonged to a lower caste.He producedThe main reason I watched Bramayugam was the audacious choice to shoot it in black and white, which turns out to be a really wise one. Without a doubt, the film is a monochromatic masterpiece. A haunting yet alluring mood is created that lasts long after the credits roll by the director Rahul Sadasivan and the breathtaking cinematography of Shehnad Jalal. Black and white is captivating. 
The remarkable casting of the picture is one of its most notable aspects. When was the last time you saw a film featuring just three characters? The three main characters of this tale—Mammootty, Arjun, and Sidharth—are what you witness in this 139-minute film. A couple more characters appear, but they do so for a very little period of time.
Here, Arjun gives the performance of his career.Brahmayugan" turns out to be a visually stunning film, a masterfully crafted work of art that makes a lasting impression on its audience. The director's ambition is immediately apparent, as he crafts an audio-visual experience that is nothing short of technically stunning. The film is a slow burner, but it does a great job of bringing viewers into its complex world little by little so that they are invested in every moment.
Though "Brahmayugan" is expertly made, its distinct narrative and nuanced political overtones might not appeal to a wide audience. However, for people like me who adore this kind of cinema, the film turns into a fascinating voyage that is worthwhile.
The political messages that were subtly woven into the story and created a smart discourse with the audience really stood out to me. Thanks every one.
