YMMV / The Punisher: Purgatory

• Audience-Alienating Era: Many fans hated the idea of Frank going from a mafia-hunting anti-hero to a supernatural force of vengeance trying to rejoin his family in the afterlife, which is likely why after Wolverine/The Punisher: Revelation, Marvel was willing to let Garth Ennis's The Punisher: Welcome Back, Frank storyline return Frank to normal.
• Complete Monster: Lord Olivier is a Hell-Lord banished for his ambition and treachery even among his devilish compatriots. Growing up into a two-bit hood known as Frank Costa and regaining his memory of his demonic life upon his first murder, Olivier reinvents himself as a feared crime boss with a legacy of murder behind him. Desiring to get back at his fellow Hell-Lords, Olivier initiates Frank Castle's fall into the Punisher by having his family murdered, foreseeing that Frank reinvents himself as a brutal, murderous Anti-Hero so Olivier may enslave the souls of every criminal he kills for his army. Along the way, Olivier has angels hunted down by the hundreds and torturously kills many himself, bathing in their blood to rejuvenate himself; tortures his loyal minions for failure; and ravages and conquers the realms of the other Hell-Lords one after another, not intent on stopping until Heaven and Hell are put under his tyrannical reign.
• Hilarious in Hindsight: This storyline had been unfavorably compared to the likes of Ghost Rider which fans deemed it to be derivative of. Cue years later when an alternate version of Frank as the Cosmic Ghost Rider would be unveiled and become an Ensemble Dark Horse.
• They Wasted a Perfectly Good Plot: The Punisher with supernatural abilities is actually an interesting concept in theory...for a one-off storyline where it was temporary.
