YMMV: Heroes Reborn
Author's Saving Throw: Heroes Reborn: The Return, the miniseries that hauled everyone back to Earth-616 once it was clear that Heroes Reborn was a failure. Before then, the second halves of the Captain America and The Avengers titles, both heavily Retooled after Liefeld rejected Marvel's new contract terms and Wildstorm took over production.
Still, the executive side of the comic book is one thing, the actual plots and arts are another. In themselves, the issues by Rob Liefeld are even worse than The Crossing, and perhaps the worst material in all the history of the Avengers.
Growing the Beard: Liefeld quit after issue 7. Walt Simonson then took over the Avengers title, penning five very well-received issues. Captain America saw similar improvements.
HSQ: The Galactus storyline was crammed with these. The first issue literally ended with the destruction of the earth, the third issue began with the the death of the Fantastic Four.
The approach to the coming of Galactus, with several heralds instead of one, and each one establishing and protecting a machine at distant places of the world instead of a single machine in New York, was used again in the animated series Avengers: Earth Mightest Heroes
Harsher in Hindsight: The first post-Liefeld Captain America issue mildly retconned Cap's backstory to reveal that the United States tried defrosting him during both The Korean War and The Vietnam War, only to put him back under when their mental conditioning started to buckle. Years later, the revelation that the Winter Soldier, formerly Earth-616 Captain America's sidekick Bucky Barnes, was kept in hibernation by the Soviets until needed made this twist horrifyingly familiar.
The Woobie: The Swordsman. He charges against Loki... and he tosses him away as if he were nothing. He charges against Kang... and he tosses him away as if he were nothing. He charges against Hulk... and goes to the hospital with massive injuries. Then Loki turns him into energy, and absorbs him. End of story. Really, why did they bother to put him there to begin with? Just because a guy with a sword could be made to look like an anime character?
