Punisher: Born
One of the best war comics ever written. "Give me the sixty"
Punisher: Army of One
The Grand Nixon Island arc should've been longer. But it's still an awesome read.
Punisher: Business As Usual, Full Auto & Streets of Laredo,
Ennis Knight's run started wavering off at this point. Aside from the hilarious Wolverine story, the stories range from decent to not great. But they fly by so quickly.
Spawn: The Undead
A very interesting change of pace from Ennis' Marvel Knights Punisher. This is a horror anthology of very sad, very human stories that we observe from Spawn's perspective. Well worth the read.
