The Punisher vol 2: Army of One - Garth Ennis

For the most part this collection is a rematch between vigilante Frank Castle (The Punisher) and the ridiculous assassin The Russian, as Castle attempts to stop a mercenary army with a WMD. Ennis lives for over the top violence and making mainstream Marvel superheroes (who usually just show up at the wrong time) look like morons, but I just can't get into it.
