Having been a long time Doctor who fan, I've recently decided to pick up Tom Baker's complete run as the 4th Doctor. Some I'd seen before, some I hadn't. This was a new adventure for me, and should have been a marvel. Baker and Ward taking the lead, with a youthful script editor Douglas Adams at the helm. There are great moments of dialogue, and it laid a few ideas down used in more recent Who outings (Like the Doctor's message on a Ming Vase in "Angels Take Manhattan". but, overall, the idea is a bit silly, and there's too much lightness to make it a classic Who. There is scope in the idea, of an alien who wants to correct his own mistake, at the cost of Humanity, and Adams reworks the plot as the core of "Dirk Gently's Holistic Detective Agency". If you're a completist, or a DA aficionado, then this is a good buy. If you want a one off example of the 4th Doctor being awesome, look elsewhere.
