Godlike Doom should have shut the Siege Perilous so the Z's and BP couldn't come through. Doom should have known this was going to happen? But like the Beyonders didn't know Doom could use time travel, Doom couldn't know the little tricks Dr Strange had hidden away either, I suppose? There are some really astounding twists to this story, about what is Dooms limitations. Doom has a bodyguard, Galactus, so why is he worried about swarms of Domain residents flocking to Doomstadt? It's like Doom is deliberately letting things slip through his grasp, like a very bad movie actor being a ham. I can almost see Doom reading the script in the background, "Oh, yes. I meet Reed in the 7th scene, in the Molecule Man dimension, and then we wrestle".
