I was fascinated to read a full length review of Tyranny of the Daleks and flattered that the writer took the time to set out their thoughts on it. I agree with a lot of the comments in it. As a fan film maker, one of the defences I've always employed is that when we made our film, the enjoyment and fun of making the film was at least as important as the finished article. At the same time though, it's fair to say that if we had the skill (and budget!) to cure it of its deficiencies we would have done so as we were keen to make it as good as we could.
