I'm going to just lay the cards on the table here. This is just a recap episode. If you've just watched the rest of the show, there's absolutely nothing about this special that is required viewing. It sums up the story nicely, and I do actually feel it would be mean to judge it harshly purely based on the quality of what it's recapping. As my review of the main show should make clear, "86" is a pretty phenomenal show, easily the best mecha show of the past few years, and that's with only half the story. As for the details of the recap episode, Ithink it does its job well enough. It's well edited, utilises the show's score well, and provides a nice summary of the show. It's restricted runtime does mean it glosses over some of the gentler character moments that I think make the show special, but ultimately, if you're watching it, you've probably already seen all of that. Skip it if you don't care, watch it passively if you're a completionist like me.
