ok...so I just finally finished Nexus via the Mill Creek DVD set. I guess I never fully watched it to the end, which would explain why I dont even remember the latter host (Ren), or how it ended.
. Every time I went to watch the show I got about a dozen episodes in, and got distracted by other things. So those first few episodes I knew well, but the latter ones were all new to me.
It was an interesting series, despite some of the jarring changes late in the show. Perhaps an attempt to course correct, that just didn't work. In hindsight some 18 years later, it is definitely a solid entry in the franchise. I enjoy it for what it is.
I'm glad they actually connected the dots between The Next and Nexus (even if it was via MIB amnesia). I thought it was going to be left as something vague told in a novel or Manga adaptation, but glad it was actually shown. I'm unclear on a few things however...
The host for the majority of the series (Himeya) was pretty clearly shown to have died, not sure how he appeared at the very end. Also Ren the latter host was supposed to be dying because the cure he needed wasn't developed, yet he still lived "somehow"??? I mean I'm all for happy endings, but not when there isn't a clear explanation, or maybe I just missed it.
The idea of an Ultraman who's power can continually be passed is a neat Idea. Tiga played with that a little bit, allowing the will of children to resurrect him once before. Also later, Zero would be shown to have this ability (having 3 hosts so far I think?), and now in retrospect, I can understand why the Captain in Ultraman X was able to be the host of Nexus on a couple of occasions (which seemed random at the time).
