Rebirth was better. Outside of the fact you were getting more with less (An 80 Page Giant for 3 bucks? I'm sold) Rebirth just ultimately had a better Narrative & a better payoff. Rebirth was this big beginning of a mystery on why a near omnipotent being changed this universe & is so deadset on keep it cold & bitter & has readers checking out titles connected to this mystery to find answers or build up. It has this impact of characters who were missing over the course of the reboot & how it effects not only the audience but the characters as well.
Legacy doesn't really have that same impact. I don't feel anything's for Logan's return since Marvel never really gave me the chance because all they did was divided him by 8 & gave them minor changes, Maybe I feel something for F4 given the BS reason for getting rid of them but it's hard to really trust Marvel on anything regarding the team. This Avengers BC stuff is cool & all but it doesn't really make me interested if this is going to be a big Earth shattering plot & more just an Avengers centric story. It's more of just a big preview for titles unrelated to one another & eh on the whole thing. I'll check out the titles simply because there's a spark of interest in those titles but that's it.
