Batman: Gotham by Gaslight was definitely an interesting take on Batman and other characters based during the murder spree of Jack the Ripper around the late 1880s/1890s. Theres also a nice little twist in there. B+ , Entertaining and a nice refreshing take of the caped crusader.
Definitely an interesting storyline and a bit of mystery up until the end which was really enjoyable. You dont really know who the bad guy is until the very end, unless I missed clues throughout the film that pointed to a certain character.
Its Definitely a Batman animated film to watch, like most of DCs animated content.
