I agree with this point here. The way other writers have handled Jason indicates to me that they just can't be bothered to put in the effort to do any research into how his character is being handled but in all honesty that's true for ANY version of him out there. Writers after Winnick ignored the direction he was headed with the character as well. There was also that snafu with Dick back doing Grayson where a writer didn't bother to check with Seeley/King to see how the character was being handled in their book and the writer had entirely the wrong vision of what was going on in that book, which brings me to Bendis and Leviathan. Bendis is the poster child for totally ignoring a characters history and also ignoring whatever it is the primary writer of that character is doing with them so no I don't believe he is giving Lobdell's book more than lip service.
If Jason and Talia patched up their relationship then it must have happened off panel, which is again another thing that Bendis is guilty of doing. He has a nasty tendency toward having really important plot points happen off panel with little to no explanation as to how things transpired to reach that point. He also has a tendency toward having characters do things out of character for the sake of the story instead of actually picking characters that already fit the story he is trying to tell.
I don't think Bendis's Jason sounds all that bad and I do like it that Bendis acknowledges that Jason is smart and savvy enough to pull something like this off even if I don't believe that Jason has any interest in doing something on this scale these days however I don't trust Bendis to do anything of note with the character either. It would be nice though if other writers would see what Bendis is doing here and that it would occur to them that Jason isn't just a dumb bruiser whose only ability is fighting.
