I know one thing, if I watch the special and don't see any of the following:
) Doctors 4-8 interacting with 11, 10 and Hurt in some way, even if it's just voiceovers (as long as its new dialogue)
) Classic series companions interacting with 11, 10 and Hurt,
Doctor Who will be over for me. It will finally prove that the new series is undeserving of the honors of the original, classic material.
