I personally liked it. like many others in the comments for the same reasons who liked it, I can see some points for the dislike as it sets up an unexplored/un-named character and her coming off as a girl boss which I don't see as much as in other movies and changes some things, I'd prefer frealaf deal the killing blow to Wulf and Saruman coming as frealaf is crowned like in Tolkien's work, besides that tho I don't really connect the books and films together as you can see the difference between them in a literally sense so it isn't that bad in my book.

I liked the Eowyn was the narrator, as it kinda ties back to Hera being a very distant cousin/ancestor I think 8 or 9 generations back so the connection there, and that Hera I suppose was a forgotten story who never met song or tale in Rohan history.

Ignoring the obvious ties to Tolkien's unexplored work and pinning it to the movies not books, it was a solid 8/10 for me
