This Cable series has probably been one of the most consistently satisfying comics that I pick up on a monthly basis. It's not really an instant classic like The Depths or All Star Superman, but it's always there and always good. Like Brandon wrote in his praises of issue 7, the series has a distinct Lone Wolf and Cub feel, especially how both Cable and Bishop are shown to both be these honorable guys but on opposite sides of the conflict.
Leading up to this issue, Cable has landed a wife and pretty much settled down to a quiet life, even burying his weapons under concrete. Meanwhile, Bishop has been captured by the X-men, now lead by uber-douche Cyclops. Some of the best moments in this issue are Bishop's response to the torture or Cyclops and the White Queen. These scenes are disturbing because Olivetti shows the pain to Bishop with drool coming out of his mouth, but also because this is the X-Men doing the torture. Only Beast is there to call Cyclops out on his dubious methods and even he's sort of lost the backbone to stand against him like a true X-Man would.
To me, this is clearly a metaphor for what's been going on with the U.S. and their policies towards torture. There's actually an interesting moment in Young X-Men #1 where the new X-Men question Cyclops' methods and he responds that everything has changed since M-day. I think Cable does a good job of showing how complex the issue is. Bishop is obviously this sicko messing with the time stream, ripping out peoples hearts and arms, and even causing global-scale catastrophes, but the comic still shows him as this guy who has honor by fighting for what he believes in.
The series has evolved each issue. It's hard now to think back to issue #1 where it had more of the tone of a 70s post-apocalyptic sci-fi movie. It's not that there have been many momentous events that have taken Cable from issue #1 to #8. The whole series can be summed up with Bishop chasing Cable through time. What has changed are the characters' personalty. Over the course of the series, you can see Bishop grow increasingly more desperate and insane, while Cable grows into the wise battle-weary father he is in this latest issue. This is what makes this series special. You can get action in any comic you pick up, but rarely do comics measure out suspense and character development like Cable.
