I just finished the 1996 movie, and it left me wondering two things, well, actually, three things.
1. Why is Eight half-human? I thought the Doctor was a full Time Lord?
2. Why is Eight considered an "official" Doctor when several other acts who have played him, like Peter Cushing, are not?
3. When does the Time War take place, since Gallifrey is alive and well in the movie?
1. Out-of-universe answer: Because Fox are idiots and thought Spock was the coolest thing ever.
In-universe answer: Because Eight is a fountain of BS, if you're going by the comics. No, really.
2. Because the Peter Cushing Doctor probably wasn't intended to be canonical in the first place. He was a human inventor who made a time machine, if memory serves, so there really doesn't seem to be a way to reconcile him with the Doctor Who "canon"...
...although note that canon is in quotation marks. The Doctor Who canon policy essentially boils down to "whatever you feel like believing, it's a time travel show". If you don't like Eight, you can ignore his adventures if you want--although the show does seem to be pretty certain there was an Eighth Doctor and he did look sort of like Paul McGann (as glimpsed in The Next Doctor, The Eleventh Hour).
3. After all the media starring Eight, it seems. I don't think any mention of the Last Great Time War is made in either the books or the audios.
