The issue with the Dredd partwork is that first 80 books had a lot of objectively crap stuff in it. I don’t fully understand the decision-making when you had volume after volume of rear matter where the creators were saying what you’d just read was shit. The extension, though, was mostly amazing.
2000 AD’s initial run had some issues with dated material and I could have done without a chunk of Sláine, but what was included felt coherent. The first extension was mostly amazing, covering a bunch of series I never thought would see print, let alone in HC. Red Seas? YASSSSS. The second extension was my off ramp. Perhaps I’ll regret that later, but I’ve felt happy in that decision so far. As for War Machine, perhaps I’ll find that nostalgia talking (same with Glimmer Rats) but I’ll have a read and chunk it on eBay if it doesn’t strike home.
