Going Postal Reviews
When they do make changes, in this film at least, they make the wrong ones. To provide more of a personal interest I suppose, they've given Moist a much more serious and guilt-ridden personality. This has come at the expense of the charm and audacity that made him such a likeable character in the first place. A lot of that is the acting of course, but the film seems to go out of its way to give him deadly serious monologues about what he's feeling, including a bookending of the first episode with Moist writing a letter of apology for being such a jerk.
It's not a terrible film by any means. It's not even bad. But it is bland and stagey and that's rather sad. The costumes look about right, although the golems are cheesy, and seeing Tywin Lannister as Lord Vetinari was a definite highlight. But other than that there isn't much to recommend about this film.
That said, it's the utter disregard for the story and numerous fundamental plot changes that ruin this attempt... and some of the changes have ruined any attempt to put later Lipwig stories on film. At best this production is "based on" Pratchett's novel, and in a series of over thirty books (to date), "based on" is nowhere near good enough.
