Brahmāstra Part One: Shiva is a visually ambitious film that attempts to create a new cinematic universe rooted in Indian mythology. The content is rich with fantasy elements and mythological lore, which is woven into a contemporary narrative. The story is engaging, though at times it leans heavily on exposition to build its world.

The screenplay is elaborate, with a mix of action, romance, and fantasy, but the pacing fluctuates. The first half is immersive and sets up the characters and mythology effectively, while the second half becomes more intense with high-stakes conflicts and action sequences. However, some viewers found the latter part slightly stretched.

The songs and music are standout elements, with Pritam Chakraborty and Simon Franglen delivering a memorable soundtrack that complements the film's mystical tone. The background score enhances the emotional and dramatic moments, adding depth to the cinematic experience.
