James "Logan" Howlett -- Wolverine -- is maybe the only X-Men character to appear in every adaptation of the franchise to date, including now nine feature films. Logan, though, is different from the eight movies that precede it in certain ways. It's R-rated. It contains many utterances of certain four-letter words. It's incredibly, and graphically, violent. It's maybe more of a neo-western set in the future than it's a comic book movie.
