It seems that the story writer didn’t know the real ramayana epic, the real reasons about the incidents, basically ismein jo logic hai wo bina haath pav ka logic hai…oops soory logic hai hi nahi kyonki jo insan ravan jaise kidnapper, rapist(can get reference in the real ramayana shlokas), highly egoistic, jo jinkon pujta unhi ki wife ke baare mein gande thoughts rakta tha, aise insaan ko accha bola insaniyat par hi daag hai…. Well bollywood se logic and good movies expect karna waisa hi hai jaise haathi ko chaddi phenana (except some patriotic movies).
