I consider there to be three main Hulk epics/eras.
Peter David's Run, Greg Pak/Jeph Loeb, and Al Ewing's current arc.
Pak and Loeb each had their own stories, but they fed off each other. Pak largely did the Green Meanie with Loeb on the Red Hulk, but they led to a lot of riffs on each other like Planet Hulk/Planet Skaar/Planet Savage/Planet Red Hulk/WWHs/WWHII, etc.
This is largely the culmination of Loeb's Red Hulk story. It's plain dumb fun, imo.
