First of all, I've seen several episodes of the Dr. Who series, but I don't follow it. It has its fan base and that's fine. If you are looking for a good Dalek adventure without getting into the whole Dalek "genesis," then this movie works well. You don't have to know all about Who-ville as a prerequisite.
There are some visual elements that needed more budget or something - miniature exteriors of the city, the burnt forest set, and the make-up on the humanoids don't quite make the grade. But the Daleks themselves inside their metal city are something to see (be sure to look for the lava lights). The Dalek robot mechanisms are very convincing, and they are very menacing as they roll around with their modulated voices trying to exterminate anything with two legs. The camera work is good - it looks like the director tried to add some interesting angles and follow shots when others maybe wouldn't bother. The cast plays well in their roles, and the story is simple and straight-forward. This is no "2001 A Space Odessey," but then again, you don't have to think too hard about what the ending really means.
This movie will probably disappoint most loyal Dr. Who followers, but it will entertain sci-fi fans who enjoy some light fare and aren't too attached to the series.
