I'll always love 3x3 Eyes, way more than it deserves. But I'm actually pretty OK with where it ended in the old Dark Horse run, and actually don't want it getting republished. That's because it's an 80s manga that ran until 2002. A while back, I tracked down scanlations of the rest of the manga and oh boy. The manga that it becomes towards the end of its run has almost nothing to do with what it started out as. Where Dark Horse stopped publishing is actually a pretty good place to jump off and just imagine a "And Their Adventures Continued..." ending, versus the gigantic clusterfuck that 3x3 Eyes turned into*. Especially when that's basically what the real ending ends up being anyways! We also only got like 7 or 8 volumes published here, but the total run is 40, and I just can't be putting that many books on my shelves, or dedicating ~$400 to a single intellectual property. Also, the guy's art style changes significantly over the course of the comic, and by the end it just doesn't look right compared to how gorgeous his illustrations are early on. There's also several spin-off/sequel manga too, but I'll probably never read those and I'm pretty sure I don't want to either after how 3x3 Eyes went.
