All those critics saying the regular two-parters need to be three-parters instead might be surprised that this one-shot is quite fulfilling.
I don't think that's a fair comparison. Arguments about optimal story length aren't some universal rule, they're about each individual story and what pacing works best for it. I don't think anyone's saying every story needs to be longer by some constant ratio, just that the particular 2-parters they've read in this series don't feel like they've fleshed out their material fully enough, that it's not enough length to really do a full adaptation/reworking of what was originally a 50-plus-minute story. Whereas a story designed to be a one-parter would tend to be conceptually tighter and more focused and could well work better at that length, since it's not intended to be a full episode adaptation.
