Yeah, I like this ... we should have done this awhile back.
Let me see ... As for what I know I am gonna try and read this week -
Was Rebirth in the top spot, but having just returned from the LCS just to say hi to peeps ... I need to change that now. I hear there are a couple issue prior that you should read first, though not a must.
1 - Justice League #50
2 - Superman #25
3 - Rebirth
(Then, as mood hits me, and when I can get the ones I don't have)
Captain America #1
Extraordinary X-Men #10
Grayson #20
Johnny Red #7
Flash 52
Nighthawk #1
Lobster Johnson: Metal Monsters of Midtown
Afterlife with Archie 2-4 (I hope)
Chilling Tales of Sabrina (3-whatever issue it is up to)
and
Rachel Rising #42, though I may sit and re-read this entire run first. I don't think I read the last 3 or 4 issues anyway, thinking I was gonna do a full read through, so yeah ... may just do that. More pushing Marvel Heroes Return to the back-burner

I am sure I won't get the full run in this week, however.
Those are the ones I know I want to tackle this week.
