Having only read some of the book, I didn't have any preconceived notions. I went in because I loved the concept, the people involved, and trusted the passion of my wife. Her affection for the show sold it more than any of the above but all of these gateways were more than enough to dive in whole heartedly.
I worried that it would either feel rushed for only having six episodes or perhaps too long. Neither proved true. I never felt it drag. Quite frankly, I've watched 90 minute films that struggled in parts to keep up the pace. This really moved from start to finish.
I have great confidence that if you're a fan of the other Terry Pratchett movies (Hogfather, Colour of Magic, Going Postal), then you will like this. If you have a passing fancy for these types of fantasies, or just like the actors, you'll also enjoy it. Everyone who interacts on screen has amazing chemistry. They make it believable.
And speaking of that, David Tennant and Michael Sheen are fabulous when they're on screen together. It's like they've been best friends their entire lives. They bounce off all the subtle physical cues, building those characters in ways that the words wouldn't do on their own.
If you watch it for no other reason, give it a chance for them. They are magical but then again, the whole series was. I can honestly say, I haven't been so charmed in a very long time. This mini-series wins.
Rating: 5 out of 5.
