4.5, rounded up.
Freed from Hell and having wrested his body back under control, Logan sets out to take down the Red Right Hand once and for all. This strange collection of characters waits for him patiently, with only the Mongrels to protect them. As Logan claws his way towards his revenge, he has no idea just how terribly the truth behind the Red Right Hand's scheme will cut him.
Act three of Jason Aaron's Wolverine epic continues much in the same vein as the previous two - the A plot sees Wolverine carving through a different member of the Mongrels per issue, while the B plot gives us flashbacks as to how certain members of the Red Right Hand came to join the group. These are many and varied, and the way that Wolverine impacted their lives is also surprisingly diverse even if it can be boiled down to 'he killed someone they loved'. These are infinitely more compelling than the A plot, since the Mongrels are fairly generic as villains, but this actually helps the final gut punch reveal land better, because they feel so inconsequential until they're absolutely not.
The final two issues of the volume act as an epilogue, as Wolverine reels from the ending of the Revenge arc. It's hard to say too much here without spoiling the reveal earlier in the story, but it's interesting how Aaron can make such a powerful story feel relevant, and also give Wolvie a recovery arc in only two issues that still feels earned and noteworthy. It could have gone on much longer, but it works really well despite the short length.
On art is the returning Renato Guedes for the main arc, then Goran Sudzuka takes over for the final two issues. His art's a little more pedestrian than I've seen it before - there's a group shot that looks very dodgy with some X-Men having oddly shaped heads, but the emotional core of the scene remains intact despite this.
Wolverine's Revenge is a story that, on the surface, seems to be one we've seen before. But it hides a dark core that stabs Wolverine right in the heart. A perfect ending to this first year or so of Aaron's run on the title, and one I won't soon forget.
