1.No Relation with Indian Vedic History[Mythology] - Bollywood ruin concept of Astra and Divyastra because as per my knowledge man can obtain Divyastra by vedic ritual, Taposadhana [ Meditation to activate Chakras and archive divine consciousness ] and training to use but man never became Divyastra itself. Bollywood even know different between Sastra Astra and Divyastra. All celestial weapons made by different god not by only lord bramha. Bollywood just indigenize x man, DC, marvel with Indian mythology. Even they don't know Bramhastra is powerful celestial weapon but Bramhasherastra and Bhamhandàstra(Bhamhadanda)are more powerful weapon than Bramhastra and to obtain these three celestial weapons man needs to make his body powerful enough with yogsadhna to become worthy of it and then needs to do Taposadhana to acquire those weapons from guru or various deities and lord nobody can obtain these celestial weapon or power by birth not even lord Parshurama, lord Ram, and lord Krishna obtained by birth they ware going through process. Here Ranbir Kapoor he become Agniastra itself. Just Imagine What agnidev and other god going through after knowing that somebody using their power without their consent 😅. No research at all. Misuse of mythology.
2.Screenplay - Love Story of Leads ruing whole adventure. Totally nonsense. We are unable to connect soul of the story. Character development is poor. Very less screen time for Nagaarjuna, SRK. Poor creativity like Vanarastra or NandiAstra. Editing is confusing. Screenplay should be trim by 20 minutes. Fail to utilize true essence of Indian culture and mythology.
3. Acting & Dialogues - why character who connected with Indian mythology would speak in Urdu instead of Sanskrit driven Hindi. Dialogues are very cringe to sound. No significant impact of any dialogue or acting which you can carry out theater. All cast are under utilize their true potential. True mannerism of Guru, Student and Gurukul discipline was missing.
4. Visual Effect & BG Music - Appreciable! but you can not hide plagiarize in name of inspiration such as Wanda and many more. We are far away from Hollywood.
