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.
The anime ending, which basically takes something that took less than seven pages to resolve and stretches it to a whole episode, and what's more, turns it more or less like something out of an action movie,and what's more not only messes with the characterization of characters — specifically Amaterasu, who in the manga who would never just sit there and watch while Uka faded away, and in fact did everything in her power to stop it — it also gives a far different message than the manga itself, in that Humans and Gods can never be compatible.
