* AuthorsSavingThrow: To mend the wounds left by ''ComicBook/CivilWar'' and ''SecretInvasion''. It might've worked.
* NightmareFuel: [[spoiler:Everything about the Void, from the {{Gorn}} of a changed Sentry ripping apart Ares to the reveal of its [[RedAndBlackAndEvilAllOver true demonic appearance]] to Sentry's charred corpse after Thor is forced to MercyKill him]].
** [[spoiler: There's also the extremely unsettling reveal of its nature as the Angel of Death. Osborn pronounces that the Void simply is Death. Its the end of all things. You'll meet him when you die, [[HeroKiller sooner]] [[WeAllDieSomeday or later.]]]]
* TheyWastedAPerfectlyGoodPlot: With Comicbook/CivilWar, [[NothingIsTheSameAnymore nothing was the same anymore]]. There were other stories like that, but always they were either set on alternate realities or possible futures, or the law was abolished or never enforced by the end of the story. For the first time, superheroes became either TheEmpire or LaResistance. With Siege, StatusQuoIsGod was restored, and the Marvel Universe returned to the dull and always seen context.
** They might have wasted it due to the buyout of Marvel by Disney, which occured at roughly the same time as Siege's release (December 2009). While it's likely a huge coincidence, there's also the possibility that the status quo was restored as a condition of the buyout.
** Norman was taking on the entire Marvel Universe, but he's still primarily Spider-Man's main villain, and it would have been nice if Spider-Man had been more involved in taking him down. All he did was get the last punch in after it did not matter anymore.
