Right up until the end, people complaining about "time travel logic"
Like, they complain seriously, as if time travel actually exists, and they are mad that it doesn't follow that real-world logic.
Sometimes I wonder if people even know what a story is. Especially a story about time travel. Hint: there is no "logic", it is entirely made up by writers, and subject to their whims.
That's true, but it's also basically irrelevant--nobody is criticizing the story on the basis of any "real-world logic." In other contexts I've certainly criticized readers for failing to distinguish between reality and fiction, but the above assertion totally ignores how stories usually work.
Time travel is a well-known fictional convention that has been depicted in a variety of different ways, using a number of different fictional explanations for why the time travel occurs and how it works. Unlike those stories, however, this series pays only negligible attention to its fictional time-travel mechanics. As others have said, the author clearly doesn't care about such matters or about answering the questions that inevitably arise when deploying the time-travel trope. That's fine--the story is what it is.
But readers can't be blamed for thinking that this author might do what 99.6% of previous time-travel authors have done--show some explanation (vague though it might be) about how the time-travel trope works, or for supplying their own readings when the author doesn't bother to do so. The suggestion that such readers "don't know about stories" is fatuous beyond belief.
