puritybrown just wrote the most awesome summary of Cable & Deadpool ever.
Now, bear in mind that this is posted in ship_manifesto, so part of it has to do with the slash/relationship aspect of the characters. But even if you have no interest in slash whatsoever, this is a GREAT read and summary of why the comic was so completely awesome, and does a good job of explaining the characters and their interactions.
GO READ IT:
(Also, ashcomp, how very convenient that someone else wrote this up right after I said I would post something explaining why I love C&DP. Well, this person did it for me!)
(Also also, she linked my recap of the Deadpool Saga. Bless.)
