Just because an author writes three interconnected novels doesn’t mean they deserve to become a movie trilogy.

The Golden Compass is expected to be the first of a trio of films based on Philip Pullman’s His Dark Materials series. In fact, it contains only enough material for half a movie, stretched to feature length. Just when the action kicks in and characters get interesting, Chris Weitz’s version ends, talky and abruptly.

Any good Part 1 leaves an audience wanting more.  The Golden Compass leaves us needing more; it plays like an extended preview trailer for coming attractions that may not come. New Line Cinema is wisely holding off sequel plans until it sees the box office returns, hedging its bet that Pullman’s readers can deliver Lord of the Rings-sized returns.

Perhaps they will, but a more thrilling introduction to Pullman’s dark fantasy world would certainly help.
