Just for entertainment purpose, this series doesn't teach actual Ramayan.
For example Ahiravan was half brother of Ravan as stated in yester years, but in this entertainment version, Ahiravan is shown as son of Ravan.
Many such instances where we get diverted through the fact and so I request producers to show content on ramayan only if it is through verified source. I am no one to judge why this series is made to teach or to entertain, but people should know your agenda, so as to perceive it accordingly.
