The Wolverine, which followed up the critical dud that was X-Men Origins: Wolverine, ends with an unexpected plot twist and an anticipated post-credits scene. But with the X-Men spinoff stuffing so many new characters together, it can be confusing for viewers to keep track. Mostly playing out as a standalone adventure within the X-Men franchise, the movie deals with Logan, a.k.a. Wolverine, flying off to Tokyo to meet an old acquaintance, who is on his deathbed. Yet as new allies and enemies are thrown into the mix, the mutant antihero must release his adamantium claws yet again.
