Mainly because I feel like your "bad points" are quite moot and not "bad" enough to merit critique.

There is a difference between "transvestite" & "gay", mainly that the former is used for looks (guy dressing up alternatively looking like a female, the latter in this case) while the latter is an actual sexual preference and a vastly overused way to define something that looks good and "unmanly". Also, coming from me, transvestite isn't even something bad. I even took the time to end the post with "and I'm lovin it".

Also, I am quite sure that there would have been more foreshadowing if the third kazekage's role was important. The only reason they mentioned him was to show us readers how badass Sasori is, thus, his existence is only a fuel for Sasori's awesomeness. Meaning that they don't HAVE to mention it 30 chapters earlier as they did with Kimimaro, who was actually a part of the story in a whole other way.
