It's aight. It's indisputable that it has heart. I'd argue it's pretty good-- or rather, if we got into it, I'd talk about why I like X and argue why you should recognize how right I am. I felt the character arcs were very thoughtfully done, and the general narrative does a good enough job in providing tinder for those personal journeys.
That general quality, and my bias towards the story,
does mean that I'm more forgiving where charity arguably isn't merited, though. There are parts I can't rationalize or find good value in, and also realize that they didn't really have any good maneuvering options given the very premise of the story.
That aside, the only other thing of note that I can think of that you haven't already totally witnessed (e.g. animation, music) but isn't explicitly spoiler territory
and is something I just felt like talking about is its romantic developments. Those are... fine. It's probably one of the weakest thing about the series, and the general way that it's carried out isn't
precisely to my liking (and that would be no shipteasing, no romcom subroutines, either one is dignifiedly loyal to the other and either is provably willing to murder beast and man alike in order to protect the other) but they're all based off of mutual respect and I never got the sense that they were totally detached from the character's main deal and therefore superfluous (and at least two of the romances have that last thing I was talking about liking, in addition to there not being any ship war bait).
Another question, has anyone else ever ran into people presenting ATLA as a "moral alternative" to anime (and thus a reason we should stop watching evil sexist anime in favor of a PC western equivalent) or am I the only one?
You... might be the first. Pretty sure ATLA had its own cheesecake.
I've never seen the cartoon personally, but I know from E;R vids that the Whorra shit is absolute cancer. I really don't feel like starting a route that ends in an inevitable dumpster fire. There's much better stuff to watch this season.
The good thing is that you don't have to bother with TLOK to enjoy ATLA, since the latter is self-contained.
