I thought The Wolverine was good, it has the same filmmaking style, themes (especially about death, like Jye and Batfan mentioned) and beats running through out it that are in Logan. It makes sense because The Wolverine and Logan both have James Mangold, Hugh Jackman, Scott Frank, and Michael McCusker behind it. You can see the direction that they were going in and what they were going for once you get to Logan.
It's that third act of The Wolverine everything takes a dip. All that goofy ****, the lame use of CGI, Silver Samurai, it just isn't as good as it was earlier.
