Actually, I liked the ending, in a sense. TBH, it reminded me of what I see as one idea in One Breath that I really really liked - yes, I know, think of it as an analogy, I guess. I'm not going for a direct similarity here ;)

I felt the part of One Breath that really did it for me was the resolution of the X thread, so as to speak. Mulder either spends the night with Scully, or he goes after those people who put her on that respirator. He doesn't have two options about it, and it shows. One thread gets left hanging, undeveloped, or shrivelled: he goes back and finds his apartment trashed, and that's just it. Period. We never ever get to see anything along that line again. And that's something I find interesting/that I liked about the ending in this one. To me, anyway. And that's that it felt like we were on the edges, alienated, watching Scully make a choice. And once that happens, endings don't happen *neat*. There aren't clean resolutions. Bits are left hanging there, and we don't really know what happens, but in the end, it all leads back to some resolution that we (guess?) that Scully might/might not have reached.
