In contrast to many late 90s minis and/or quickly cancelled series (hard to tell the difference at times, as the still ongoing practice of "maybe it's an ongoing if you all buy it" is definitely in place by '99) I've slogged through, Galactus the Devourer was a delightful surprise. I read it in the first place because Louise Simonson's Warlock run (about the former New Mutant alien technarch, not the other Warlock) fit into my expansive X-book readthrough, and it had a bunch of footnotes doing cross promotion for Galactus the Devourer, which was also written by Simonson. Warlock was alright but not amazing, but I thought I'd give Galactus the Devourer a chance to see what Simonson's other return to Marvel writing was like, and my expectations were definitely exceeded.
A big part of this is that it has pencils by Sal Buscema and (very significantly) inks by Bill Sienkiewicz!!! In this era, it's typical to only see Sienkiewicz on a book for maybe one particularly moody fill-in, or a cover, but here they got him for all 6 issues and he's doing amazing work. Louise Simonson has often been asked to do a lot of Marvel books targetting audiences on the younger end of the spectrum of comics readers, but here she's being allowed to operate on less explicitly juvenile register. This isn't to slight her other work. I think Simonson/Brigman Power Pack is probably one of the best Marvel books of all time. But this is a great opportunity for her to show off her ability to write outside of what she's been asked to do so often (and what she was doing in Warlock) at Marvel, and she nails it.
It reads like the ideal version of an Event Series, but without the burden of actually having to support a line-wide crossover. It's just a self-contained story with enormous stakes operating on a huge scale. Galactus is the title character, but in practice the protagonists are Silver Surfer and Alicia Masters (during an era where she can transform into a super her) as they work with a broad cast of Marvel characters to deal with a Galactus who has developed an addiction to consuming only the life force of planets, creating a kind of vicious cycle where he never feels sated. Just a really strong bread and butter superhero story at time when a lot of books were floundering.
