While my first instinct is to laugh at this message, all the same maybe someone might get some new perspective out of my reply so I’ll answer. First of all, I think it’s genuinely hilarious that people accuse Tauriel of being “good at everything” in a world where some of the most famous figures are insanely talented at everything. Quite frankly, I think it’s sexist that people are so willing to dismiss Tauriel for being a skilled warrior and accomplished healer when you have characters like Aragorn, Elrond and Glorfindel that no one seems to bat an eye at. (I utterly, wholly detest people talking about ‘Mary-Sues’ but if there was a male equivalent following that logic, lord almighty it would be Aragorn).
Additionally, I think saying Tauriel “betraying” Thranduil is absolutely ridiculous (and for the record, we don’t know that she’ll ‘get away’ with it) and by the same logic, then Legolas also betrayed his father and king by willingly going with her. Did Tauriel disobey? Absolutely, but by no means does that constitute an accusation of betrayal. While I understand Thranduil’s desire to isolate his kingdom, I think Tauriel’s desire to leave the only home she’s ever known to protect a world she knows nothing of is a profoundly selfless, courageous act. Are we really criticizing Tauriel for wanting to save a life and battle what evil she thinks threatens the Free Peoples?? Should we not admire Tauriel for seeing beyond the prejudices of her own kin and lord to want to cast her lot with a world she has never known, but feels she is called to protect and preserve?
(Also, in the films Faramir blatantly disobeys Denethor by allowing Frodo and Sam to pass through Ithilien with the Ring and I’ve never heard anyone accuse him of betraying his father? And, in the books Beregond directly disobeys Denethor to help save Faramir and is pardoned/rewarded by Aragorn if you want a canonical example)
Finally, while her healing skills may not be common within lore & canon, I hate to spoil things for you but half of the Hobbit films thus far haven’t been canonical. I find it strange that I don’t see posts ranting about the expanded roles of Radagast and Azog, as well as the inclusion of the Nazgul who have apparently been broken free of tombs shattering the fundamental history of the latter Third Age.
While her healing may (I’d argue not really) break canon, I’m totally fine with it. Why? Because I think breaking canon is worth it to show young girls that a nuanced female character can exist within the story of The Hobbit.Tauriel is a warrior, yes, and she can kill, but she can also heal and care and love. She acts with her own agency and wants desperately to protect a world she has never known and folk she has been taught all her life to despite and distrust.
In short, my reply to you can be summarized as followed:
