Just like a book / film etc that uses any other tool, I guess.



I would argue that. I've watched Memento, but have never heard of Anabasis.



Well, it would be pretty hard to accept the central themes of Fantasy / Sci-fi if the narrator wasn't reliable. Instead of magic, who's to say it isn't just sufficiently advanced tech (and considering the usual setting of fantasy, we might not consider it to be all that advanced). Sci-fi would probably stand up a little better, but could easily come out looking like a fisherman's tale (as in a tall tale).



No, unless the novel gives me some specific reason to consider that. Why? Mostly it isn't used, so it's not worth looking for. Also, it's more of a surprise when it is used that way.

For example, Momento counts I guess... It was pretty obvious that the narrator wasn't reliable. I was also pretty sure that spoiler his notes weren't accurate either.

In retrospect, I should have guessed that spoiler his memories from before the accident weren't accurate either, considering the clues that were dropped during the film. I guess that was just this assumption in effect.

I am, of course, more than happy to explain plot holes away with this assumption.



Of course. Well, I do it more passively most of the time but I would actively reasess this whenever the narrator says something that doesn't seem believable within the context of the story. There are also other triggers. The narrator having memory problems are a good indication. The film / book being labled as a "mind screw" is a pretty good one. Seeing spoilers pasted all over the internet is unfortunately another really good indication. Thanks for spoiling Fight Club, people on other sites. This is why I like to err on the side of covering up major spoilers even if I think everyone has already seen / read the work. When I remember, that is...



No. They are interesting, but I wouldn't like to read that style of book all the time because it gets too damn tiring trying to form a coherent story.
