Adipurush might have been good if they'd pay attention to minute details like:
1) No fights of Hanuman ji with the monster during the passage over the sea and the lankini at lanka.
2) Indrajit says it's "navami" the next day while we can see the full moon on the screen.
3) Actually there's no sita maa involved during the war as portrayed in the movie.
4) Lanka is made of gold which is not taken seriously in the movie.
5) Vaali is assassinated in the first attempt in the movie which is not the case.
6) Raavan's death missed too many details.
