DC Comics' first answer to Ultimate Marvel. In 2005, DC decided to establish a new line of titles to re-interpret its heroes.
All-Star's purpose was a bit different, though. Instead of creating a second DC Universe, the focus was on taking an "all star" lineup of the biggest comic creators, and giving them the freedom to do whatever they like with DC's most iconic heroes. Thus, the All-Star books were totally self-contained, with no connection to each other or to any other previous continuity (although both creators have connected them to previous works).
Only two titles were released in this series: All-Star Batman & Robin, the Boy Wonder and All-Star Superman. Reception for both was as different as night and day. While Frank Quitely and Grant Morrison's All-Star Superman was well received, won a pile of industry awards, and is generally considered one of the best Superman stories of all time, Frank Miller and Jim Lee's All-Star Batman received derision for its hilariously awful dialogue, Sociopathic Hero cast, and the fact that most characters act nothing like they do in the original comics. Plus its constant slipping schedule didn't help matters at all; eventually it became an Orphaned Series after its tenth issue, although it was never officially cancelled. Some argued that Frank Miller was doing an intentional Stealth Parody of himself (though he did say that ASBAR is Canon with Batman: The Dark Knight Returns), while others just thought he had lost his mind.
In 2016-2017, Scott Snyder wrote a new All-Star Batman series as part of the Rebirth line, primarily inspired by his love of All-Star Superman. This series was not a continuation of Miller's All-Star Batman despite the title, as Snyder points out there has never been an All-Star Batman, only All-Star Batman & Robin, The Boy Wonder.
