Well, I chose to not even bother with this one, as there was a freakin' ton of tie-in and crossover titles. I have not had as much money for comics lately, so I decided to totally pass on this whole series.
Now there is a 12-issue "The Fearless" follow-up, and I will not bother with that either. I wonder just how long Marvel is going to drag this particular storyline out for, I think it's kind of annoying, to be honest!
I forgot to mention that this storyline was followed up with a multi-title crossover story called "Shattered Heroes". In it, a new God Of Thunder is revealed, as well as the re-uniting of the Defenders, this time with a different member lineup.
As for "The Fearless" series, that is considered part of SH. But I will still not bother with any of it. There is something else coming up in Marvel that I think will be a lot better...
