Joss Whedon's Astonishing X-Men

Joss Whedon and John Cassaday's Astonishing X-Men (2004-2008) is widely regarded as the best X-Men run of the 2000s. Following Grant Morrison's radical deconstruction, Whedon rebuilt the X-Men as superheroes — putting them back in costumes, giving them a mission, and crafting four tightly plotted arcs with a Buffy-caliber mix of action, humor, and heartbreak. The run is best known for Kitty Pryde's return to prominence, the introduction of the mutant cure, Colossus's resurrection, and one of the most devastating endings in X-Men history.
