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.
Badass Decay: Ravana has been changed in his portrayal of being a Big Bad to an Anti-Hero whose one weakness was kidnapping women that were not his. To be fair, some passages of Valmiki somewhat lead to this interpretation. See Draco in Leather Pants below, which perhaps makes this one of the oldest ones ever.
Draco in Leather Pants: Ravana, believe it or not! Numerous alternative versions (Kamban's for eg.) show him as a king esteemed for his knowledge, fighting prowess and talent in the arts and he's has a place in Shiva temples in the South, thus making this trope Older Than Feudalism.
Unfortunate Implications: The ideal setting of the story is described, among other things, by stating that everyone performed their duty according to their respective varna and asrama. A certain Śūdra decides towards the end of the work to perform Vedic rites, which causes the death of a Brahminís son; Rama then proceeds to decapitate the Śūdra, and the gods produce a rain of flowers to show their satisfaction. Mind you, most of the Śūdravarṇa is composed of non-Aryansnote the Indo-European group, not the allegedly Ďpure-bloodedí Germanic people, and judging by the fact that the non-human races are actually thinly-veiled metaphors for non-Aryan peoples (as any textbook about the subject would tell you), and the way Sugrīva simply accepts it when Rama tells him he could hunt him (since being a monkey makes him fair game)... Well, letís just say this work isnít all that well-received among many non-religious and/or non-Aryan people.
The epilogue of Ramayana deconstructs the very code it supposedly espouses. Rama is forced to part with his beloved wife Sita because of her "tarnished" reputation and in the end she decides she no longer loves him and leaves him forever.
