Thanks for the article. I'll have to read it in the morning.

I suppose you are right with this particular case. I've read essays and watched video essays where they go through the plot almost point by point but the ones I consume do have the reviewer's voice and thoughts on them.

Never have I came across just retelling of them. Well that's a lie, I did, but not frequent enough.

Edit: also to add, Japanese IP holders do turn a blind eye for the most part with doujinshi, which commonly are derivative enough from the source IP.
