I am not a fujoshi.
I do not particularly like gratutitous homoerotic themes in fiction. If you can tell a good story about gay characters, I don’t mind, but if you’re going to throw in some gay-ness just to please the fujoshi, or just to please the politically correct, I have better things to do with my time.
I think Samurai Flamenco was a very intelligent satire about the limitations of conventional Japanese adventure fiction. Adventure fiction characters are so stilted and unrealistic that anyone who acted like that in the real world would have some serious sexual irregularities. The gay theme is popular, so that’s an easy spin to put on adventure characters who lack normal sexuality.
Viewed in that light, it was a decent satire with good production values.
Viewed as anything else, I would regard it as a disappointment.
I really do respect writers who manage to depict sexually unusual characters in a meaningful, humanistic way. Two very horrible but very skillfully written stories come to mind.
The first is Berserk. It is a well-written, horrifying story about horrible events. Several characters have some sexual irregularities.
The second is Gantz. It is rather well-written, with a very convincing harshness to its realism that helps to compensate for some of its heavy-handed lack of polish. Its events are not so horrible; they call the phrase “the banality of evil” to mind. The characters are not sexually perverse, just frustrated and unhappy, so they think about sex a lot.
