For the comic:
- Dork Age: Oh, boy... This story is infamous for "revealing" that Tony Stark was in the thrall of Kang since day one and killing people, introducing Teen Tony, Mantis joining with Kang, and Wasp becoming a mutated wasp-like creature. Thankfully, Onslaught and Heroes Reborn mercy-killed it and when Heroes Return happened, adult Tony was resurrected and back on the side of good and Wasp was back to her old self. Avengers Forever also helped to undo the damage by retconning that Tony was being manipulated by Immortus for only months and the "Mantis" seen in Crossing and many of the people helping "Kang" were Space Phantoms.
- The sad thing is that the whole point of the saga was to finish a previous Dork Age, the one where the Avengers all used brown jackets and became more agressive; The Crossing retconned Deathcry into a young Shi'Ar whose extreme warrior views were a facade to protect herself, Vision had recently recovered his feelings and tried to rekindle his relationship to Wanda, Kang's "sons" Tobias and Malachi were going to be Vision and Wanda's lost sons, the Wasp's transformation was a way to take her back from retirement, etc. The problem was that the story and following issues left so many stuff Left Hanging and it wasn't solved due to Onslaught turning a new page.
- The whole thing was especially irritating for Iron Man fans, following a solid run by Len Kaminski that had set Tony up to be an active do-gooder both as Iron Man and as head of Stark Enterprises. And then Terry Kavanagh comes in and scrap all that for an ill-received Face–Heel Turn. And bear in mind, Kavanagh was also the guy who pitched The Clone Saga.
- Villain Sue: While most villains on the saga had advantages and disadvantages, Neut was portrayed as totally invincible.
