I learned a long time ago to stop letting shit like this bother me anymore and just ignore it completely. Hun isn't even my favorite villain (although he's a more worthwhile contribution to the overall Turtles mythology then the rest outside the source material), but he doesn't deserved to be humiliated along with everyone else in this slop.
You know I don't even believe The Last Ronin will be "Rated R" as these studios don't care what a writer wants, but rather what they want, however it has to be a balls deep action-to-action flick as this point. If it fails, then the Turtles will basically be the humiliated comic book property in the landscape like it's been since Laird sold the rights all those years ago.
