I don't think it has any integrity as a story, but I'm enjoying Infinite Crisis a lot, and I'm looking forward to 52 because of Morrie's involvement and the main characters they chose (I love Question, Animalman, Steel and Booster, and don't mind the others). At DC they're doing a great job at keeping things exciting. Marvel, on the other hand, seems like it's pulling crossovers out of its ass to keep up with DC. At DC they may be using an old idea for their crossover, but with Marvel it's even worse because they're using old ideas for several crossovers:
- House of M is the typical "alternate reality" "OH YES KIDS IT'S REALLY HAPPENING! oh wait now it's not" crossover. They promised consequences, but they're flawed: Spidey's angst seems to be playing anywhere but in his own titles, because they were already involved in another (convulted and lame) crossover; Wolvie remembering his origin is a good idea, but let's see how they use it; "Deadly Genesis" is a poorly written "Identity Crisis" rip off, in both premise and style; "Son of M" is actually pretty good; the "No More Mutans" shit is practically useless because 99% of the important mutants "just happened" to be unaffected by it.
- Annhilation is supposed to explore and revitilize Marvel's cosmic side, because it's been neglected for years. That was exactly what The Rann-Thannagar War was for.
- Civil War: I wonder what period they're trying to appeal to with the name War. Maybe something close to a Crisis? Hero vs. Hero? Oh my Gob, we've never seen that in the Marvel Universe. There's a spin on it this time, though: It involves a superhero registration act. What an Incredible idea, to make the Watchmen register! Of course, this will end with Iron Man saying "What have I done?? What have I caused??" and Cap replying "You did what you thought was right. Let us fuck."

Maybe some of these books are more understandable on their own without reading the tie-ins, but they cause the opposite problem: they make the characters' own continuity convulted, because they're supposed to be affected by all these crossovers at once, and sometimes by their own internal crossovers at the same time.
