If you want know about original story you can read mahawamsa. This movie not presenting original story of sinhabahu.
Otherwise it's like typical kings story ...iam not surprised 🙂
I gave this movie only 3 or 4 Stars beacuse of not presenting original story in mahawamsa. History can be unreal but we have to allow it remain as it is..if not All story, tales of the history will recreate like new version of thkat story ..story 2.0 🌝
In orginal story sinhabahus' father not human he is Lion ok it unreal..in orginal story sunhabahu married his sister sinhaseevali but it not impossible... besides these storyline change it just another srilankan movie.
