Man, as someone familiar with the ins and outs of the Alien fan edit, I gotta admit these narrative changes are disappointing.
Alien 3, apart from maybe Covenant, is the only Alien movie that actively does not care if you like it. It's divisive, it's mean, and it's ruthless in how much it wants to get that across to viewers. And I think that's a large part of what makes it a great film. Over the years it's become second to the original for me.
While I can understand why you'd want to make Dillon someone to root for - the point is that you can't, or rather, shouldn't. His acts of redemption throughout the film don't make him a good person - just a better person than he once was. And if you can leave this plane of existence a better person than you were before you were pitted against the scariest, most gruesome creature in the galaxy, well that just shows you how hopeful Alien 3 also is! To echo what's been said, the worst of the worst saved the galaxy in Alien 3, with Ripley being their guiding light of redemption.
I do hope that the editor rethinks the narrative decisions, because the color corrected effects in the 4k package would've made this the definitive edition for me.
