Heh heh heh.....Liefield.
I didn't know he was still around.
A brief history of Rob Liefeld for those who weren't reading comics 15 years ago:
Liefeld came to public attention as a decent artist while working at DC (Hawk & Dove miniseries) and Marvel (X-Factor #39). He was given a stint at New Mutants where he co-created Cable and relaunched the title as X-Force at the height of the comic book boom in early 90's. He was a popular artist with a growing fan base.
Cable became a popular character during these years and the X-titles (like most comics) were selling very well. Unfortunately, Liefeld felt that he deserved more credit for Cable (despite playing down the fact that he was a
co-creator) and dramatically quit Marvel to co-found Image Comics with Jim Lee and Tod McFarlane.
Liefield took his concept for a new Teen Titans series and created Youngblood - amid much multiple cover fanfare that blighted the industry at the time. While the hype around Image meant that the initial issues of Youngblood sold well, Liefeld was unable to produce his titles on time resulting in huge delays at the newsstand. Also, unlike Lee and Mc Farlane, Liefeld strangely started created a glut of unoriginal characters imitating well-known heroes (or "spin offs" as Liefeld calls them), further adding to the delays. Fans became dissatisfied with the inconsistent scheduling during this period. Youngblood was abruptly announced a "miniseries" to cover the inconsistencies, only to have more Youngblood titles announced and launched. Fans began to complain that his issues consisted of nothing but double-splash pages of rushed, sub-standard artwork featuring gun-toting characters
Liefield seemed oblivious to the growing dissatisfaction with his work and frequently did interviews ridiculing DC and Marvel and gloating at his independent success. His strange behaviour reached a height in 1991 when he announced his Doom's IV movie was in production (a Fantastic Four "spin-off") and released a miniseries of the film before the deal was finalised. The film was never produced.
Finally the over-supply of comics (thanks in no small part to Image) resulted in the comic industry crash. The Image "collectors issues" dropped in value from over $100 to $5-$10. Liefeld turned on his Image co-founders, took his characters and left the company. This resulted in titles like Spawn re-writing continuity (since Liefield's character "Chapel" was Spawns original killer). While most remaining Image titles continued publication, Liefield's characters mostly faded into oblivion (with the exception of Supreme thanks to Allan Moore).
In 1997 Liefeld returned to Marvel with other Image co-founders to launch the "Heroes Reborn" titles. Liefeld took over Captain America for a 12 issue revamp. Unfortunately the title performed poorly with many fans criticising the changes in Captain America's costume, along with the familiar too-frequent splash-pages filled with identical looking characters. Liefield was embarrassingly dumped as artist and once again left Marvel on bad terms.
These days Liefeld can be found on internet message boards arguing with kids and trying to convince people (that have never heard of him) that he's a creative giant.
OK that last crack was harsh.
But Liefeld was always an average artist who rated himself alongside the best in the business. He has frequently mouthed off to get attention and has made a habit of ridiculing DC over the years due to problems he has had with them in the past.
Superman Returns will be hyped by the audiences who have seen it.The positive feedback that X3 lacked. I'll be a masterpiece. As for Liefeld, he is entitled to an opinion, but a he is sadly lacking in his reasoning. Thank God he is not supervising SR! When
