I am all about canon. I love having references and a 'guide' as it were. I'm not saying stories should be stopped dead in their tracks if they need to change something small from the past in order to tell a good tale, but I'd much rather the writers adhere to whats been instead of just steamrolling through it.
I'd agree up to a point, but quite often there's the problem of which canon to follow. Take the origin of the Daleks - there are quite distinct differences between the story as told in The Daleks and Genesis. Come to that, Terry Nation started mucking around with Dalek canon from The Dalek Invasion of Earth. A lot of other things are the same. So while I do like it when stories are tied back into something from the classic series, trying to treat canon as absolute would just get your head spinning round and exploding.
