YMMV / TMNT: Secrets of the Sewers

• Harsher in Hindsight: Baxter Stockman's depiction as an amoral sociopath who doesn't care about ethics, so long as he can perform his experiments. The one he has in Teenage Mutant Ninja Turtles: The Last Ronin manages to be even worse, due to his helping Oroku Hiroto turn Manhattan into a dystopia, his experimentation on Professor Honeycutt, and being responsible for most of the Turtles' deaths, among other things.
