These are the runs I continually come back around to each year. In no order at all:
Uncanny X-Men #94 -200, especially Claremont/Bryne
John Bryne's run on Fantastic Four
Walt Simonson's run on Thor
Frank Miller's work on Daredevil (including original run, Born Again, Man Without Fear mini)
David Michelinie's second run on Iron Man alongside Bob Layton and Mark Bright
Matt Wagner on Mage the Hero Discovered, Mage the Hero Defined, and Grendel
Chuck Dixon on Airboy for Eclipse
Wolfman/Perez on New Teen Titans
Avengers Forever mini by Busiek and Pacheco
For start let me say that my quoting you is nothing personal, you just conveniently talk about a lot of runs Ive reread in one easy to get to place...
Now I loved the majority of these when they first came out, but on rereading them a couple of years ago they mostly disappoint now...Byrnes FF, Laytons Iron Man, Perez on Titans, Busieks Avengers Forever,and Walts Thor are ALL books I want to love, but just cant get into now. Just starting Mage, and always enjoyed the little Grendel I could find, but have read next to no Usagi (and saw little to get excited about).
As for the pakehafulla all-time Top 5 rereadem an weep listorama
Legion of Super-Heroes by Levitz and Giffen/Lightle/LaRocque (so like 285 - 319ish, and 1 - 60 of the Baxter). Preacher Daredevil: The Miller Years Captain America: Winter Soldier(Bru's whole dang sagarama folks) Warlock by Starlin
This of course leaves no room for Moore's Swamp-Thing or The Ultimates or Marvel Zombies or Walking Dead or Jon Sable or massive amounts of 2000AD or Fables(now that Ive read it once ) or Kingdom Come or Avengers 160 - 200 or ...
It was the year of fire… the year of destruction… the year we took back what was ours. It was the year of rebirth… the year of great sadness… the year of pain… and the year of joy. It was a new age. It was the end of history. It was the year everything changed.
I especially liked the Big Event crossovers during Ann Nocenti's run. She managed to turn turkeys like "Fall of the Mutants", "Inferno" and "Acts of vengeance" into masterpieces... at least in Daredevil.
Her Ultron was particularly brilliant and completely offbeat!
