As a point of interest, I remember watching the TV movie when it first aired. For me, Doctor Who had ended just before I started secondary school and the TV movie aired just after I'd finished. For a teenager, that was an age of a gap where the show wasn't running!
Remember, this was in the days before forums like this. All I knew about the TV movie was that it was a joint UK/US production and a well-regarded British actor was playing the Doctor. I went into it expecting it to completely ignore everything that came before and to be essentially a reboot. So I was quite surprised when it opened with a retooling of the original theme song AND then had Sylvester McCoy playing the Doctor! Sylvester McCoy, also acknowledging that he was the 7th Doctor! The Master was the main villain. The Daleks got a name-drop. Gallifrey was mentioned.
I wasn't expecting this. I was expecting a totally clean slate, but here they were, carrying on like it was not a new series, but the beginning of a new season of a long-running show. It actually showed more connection to the classic show than "Rose" did in 2005. "Rose" could have been the first episode of a rebooted show, based on its content alone. The TV movie was, without doubt, intended to be a direct follow-on to the old series.
I just thought that was worth sharing, as a classic series fan who actually expected the TV movie/new-series pilot to be cleanly separated from what came before. It was not in any way separate. In fact, it made a clear and decisive effort to attach itself to what came before.
