Well. "Doctor Who and the Daleks" was... interesting. Certainly quite campy, and amusing in its terribleness. What's the story with the canon-ness of the Doctor being the "grandfather"? Is there anything (other than the existence of Daleks and the TARDIS) in this movie that *is* taken as canon?
Virtually all fans, if not
every fan, likely consider the two Peter Cushing movies to be non-canonical. They were film adaptations of two stories from the television series, and do contradict them (and the rest of the series) in several ways, some of them quite extreme (then again, they
do follow the TV versions closely in spots, so some of what you saw is a brightly-colored mirror of canon events, if you get my drift).
The Doctor
is a grandfather in the television series, but only to Susan. Barbara and Ian are quite different characters entirely - Ian, especially, isn't the comic relief. Both Barbara and Susan are older in the television series, while Susan and the Doctor are much more alien and mysterious (and the Doctor, almost sinister at times). The whole tone of the television series is much more subdued and less camp (by a long shot), with the monochrome actually working to create a more mysterious, eerie, and, at time, frightening environment (and a lot more claustraphobic, due to the cramped sets). But, conversely, a lot of the underlying plot does remain the same from the televised version to the movie...
Ideally, the thing you should do is to watch the original Dalek serial when the Beginning DVD set comes out in a few weeks. Then you can compare the two versions, as well as finding out how the series
really began.
