It seems like this is one of those shows people are rewatching now, as if they've run out of newer things and know this is at worst Star Trek comfort food. I am nearing the end of the whole series.

I liked Tuvix. What I don't like is that it's never ever mentioned again. The lack of serialization for anyone but the Doctor and Seven - and maybe for Torres and Paris - is understandable for the era but so frustrating. And this was parallel with/after DS9, so it's not like Trek hadn't discovered serialization.
