I'd like JNT to have had the opportunity to produce more seasons as good as S25/S26
I'm glad the series ended on as much of a high as it did and glad that we got the VNAs, my favorite tie-in novels ever, to continue where S26 left off.
Not that I would complain if someone showed me an amazing S27 from an alt. universe, of course.
and I wish RTD had left with Eccleston.
