Your thoughts on brother and sister and en general, general sibling complexes

I would say it depends on the anime. But..sometimes these sibling complexes creep me out a bit.

I find that it can be incredibly interesting, at times. Other times, it's really a bit too much and it annoys me. I think it's really just how the characters are portrayed, though... if they are portrayed well, then I don't tend to have any problems with the way that characters act, in any way, whether it be a boyfriend/girlfriend relationship, o a sibling relationship, parent/child relationship, o just any kind of relationship, really.
