The timestream rule is a good and sound principle for time travel stories to operate on. I have a minor problem with "The Girl in the Fireplace" in that it appears to break the rule just by existing -- by going through the different time windows, surely the Doctor is entering different points in Renette's timestream? Or if he's not, why can't he use the TARDIS to get to the final attack, rather than breaking the window with a horse? You have to add another level of justification about "common time" to have it all make sense -- which is ok, but as I said, it just foregrounds the fact that the timestream rule is an arbitrary one, there to make the stories make sense rather than for any other reason.
