Indeed, for me, it reinvented the idea of time travel in the same way that Dirk Gently's Holistic Detective Agency and, later, Steve Moffat's Continuity Errors would do.
And what Frank Miller created, and Walt Simonson so wonderfully executed was a very entertainingly visual way of showing the effects of time travel, that Age Of Ultron would ape but not match decades later.
And now it's back, repackaged, Robocop Vs Terminator from Dark Horse Comics. And, since Dark Horse won't have the new Xerxes comic to accompany the release of the second 300 movie, this might do in a pinch.
Available in both a hardcover collection and a "gallery edition", Robocop Vs Terminator not only found an entertaining way to marry the two continuities, with Robocop seen as an early Terminator prototype, but with time traveller after time traveller trying to change the continuity, expressed in waves rolling across reality, but giving those affected the chance to send one more time traveller back to change things again before the new changes kicked in.
Yeah, I loved it.
It's also a chance for Dark Horse to do their own ripping off of Scott Dunbier's Artists Edition volumes at IDW- joining the line of Dynamite and Titan Comics who have done the same. "Gallery Edition" is the name for their line, again, reproducing the original art boards, the closest you'll get to owning the original art for less than the cost of one page.
RoboCop versus The Terminator hardcover graphic novel collection will be out on July 2nd for $24.99 and the gallery edition on July 9th for $125.00.
