I don't mind them turning Galactus back from the Lifebringer! I like the idea, but Marvel hasn't done much with the Lifebringer. I'd like to see where the Surfer's story goes from here.
I actually thought they should have made the Silver Surfer the Lifebringer Galactus's herald. At least for a bit.
It seems both obvious, and ripe for possibilities.
Unless I missed some comics, somewhere. It si possible, I pick up most Silver Surfer centered stories that come out, but my interest in Marvel these days has been less than total.
