You might not need a reason to check out any movie with a member of the X-Men… until you see the trailer. Logan is a very different spin on a film based on a comic, which is why it’s potentially brilliant.
Though the movie has been referenced in connection with the comic Old Man Logan, there are few similarities. That said, a world in which most mutants are apparently gone, Wolverine has scars, and everything is washed in depression should be worth every minute. Besides, if the trailer can be believed Hugh Jackman and Patrick Stewart are going to have to get a lot of time together, and that’s just awesome.
