Batman gets Arthur Conan Doyle and Robert Louise Stevenson treatment. If one can pass by dark knight's ridiculous outfit design, one can appreciate revisions of the characters where each finds its place and purpose in this elsewhere universe. But even with all that and R rating, there's a sense of "been there, done that". So, it ends as less entertaining than the premise or source material promised.
Yet another dud by Sam Liu, boring art-style, cheap animation, poor direction, poor and at times bizzare choice of changes from the original comic, awful sexploitation of female characters. Please DC get someone else for future adaptations.
