In spite of criticisms, the movie resonated well with its visual effects and background music. Though the amateurish dialogues fail to bring in the fantastical element in the cinema on which the story is based, the concept has a mighty feel. The characters are not grounded in the story well enough making the storyline poorly executed.
The three-part story fails to give an explanation of basic facts like why Amrita chose an orphanage to raise her child or why the senior members of Brahmansh failed to join the battle and left the Secret Society in the hands of some amateur members or why the weapons were taken away when the Brahmastra still needed to be protected.
The story could have been given a bit of background rather than a few sudden dumping of exposure in the middle of intense situations. Another thing that had a jarring effect was the unwanted use of sarcasm in unwanted scenes.
Would I still want to rewatch the movie? I would certainly rewatch it and would also want to see how the story unfolds and see whether the weakness of the first part can be resolved in its later parts.
