After recently reading a couple of histories on how 2000AD was started and developed, I thought I'd treat myself to a couple of main arc Judge Dredd collections I never read before.
The first was The Pit, which I think was said to have been inspired in part by the The Wire TV series. It was interesting, but I think I was expecting something a little more focused on social commentary and political issues. It was an interesting collection of interconnected subplots, but I was left feeling that it was missing a killer punch.
The second was Origins, which gives a lot of backstory on how the Judges came to power. Unfortunately, that's most of what it is - just backstory, written into a small-time journey into the Cursed Earth to give Dredd a chance to recount the history. It was nice to see how old story threads came together, but the story ended with no sense of anything having changed because of anything new - despite some pretty major revelations. Perhaps their effect comes into later stories. Either way, I saw this was repeatedly recommended as a "must read", but IMO you really have to be a big Dredd fan to get the most from this.
I was going to also get the two Tour of Duty collections, and the three Day of Chaos ones, but I think I'll put those on hold for the moment.
