These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: The shadow puppets are voiced by people from various regions of India who each grew up hearing different versions of the story. They point out their different interpretations of the characters and their actions.
Awesome Music: Quite a bit. Even if you don't like jazz, there is quite a few original/other songs that work really well in the film and just sound awesome.
Most notably the song fans have dubbed Sita's Fire for lack of an official name.
Rama: Um...h-hey! Sita! How would you like to take, uh, a little trip?
Sita: But we just got here!
Rama: That's good! Get packing.
And most of the shadow puppet's ad-lib dialog. Bonus points for the animation keeping up with it (particularly when Rama's father dies and re-dies while his cause of death is still being discussed. It's Buffy-Vision).
