This I think (and I see I am not the only one) is where the series starts to forge away in a new direction with the creation of its own villain- yes you have an inclining of it in the fact we are referring to the nautilus and Captain Nemo - again you have the literary nod to the Verne classic but this time they do not incorporate it in to the storyline. Instead you see the creation of the time wars own super villain - now as much as I enjoyed the idea (hey who does not need their own super villain after all) but you feel it is acting as distraction from the bigger picture - or was that just me
What do You think about The Nautilus Sanction (1999)?
