Fear Itself Homefront #1 was boring, the only interesting story of the 3 was the agents of Atlas one because it's such a weird group. Did we really need another story about Speedball making up for Civil War?
Journey Into Mystery #622 was great and my favorite so far along with Fear Itself #1. Between this and Agent if Asgard I'm really into Loki lately, I need to read his young avengers run one of these days.
Invincible Ironman #503 is barely a tie-in at all, and it's the conclusion of some doc ock story I didn't read. Tony grovelling to Otto and calling him master was pretty funny, but maybe that's because I'm not a big fan of Tony. Also it has the worst Salvador Laroca art I've ever seen, and I'm usually a fan of his work (on X books at least), it doesn't even look like his art. There's a cute little 5 or 6 page story at the end of the issue about how Tony's dad met his mom, I quite enjoyed that at least.
