What's right with it? It's unlike any film you've ever seen. But in a good way. Mixing Kevin (Clerks, Chasing Amy) Smith's charming and witty rapid-fire dialogue with an underlying philosophical enquiry into the nature of faith, it manages to be simultaneously flat-out funny and though-provoking. The fantastic cast are all on fine form, particularly Affleck and Damon bouncing off each other in superb style and Jason Mewes (as spliffhead "prophet" Jay), who gets most of the film's best one-liners and delivers them with aplomb. But perhaps most surprising of all is the climactic appearance of a certain warbling Canadian songstress as the Supreme Being, who manages to be warmly amusing without uttering a word. And it's that final scene which elevates the film to the level of something special, uniting all the characters, tying up all the plot threads and sending you out of the cinema with a massive grin on your face and a warm glow inside - even if you're a confirmed non-believer.

What's wrong with it? Everyone spends a lot of the time asking, or else explaining, what's going on. Some will find it far too wordy, too preachy with too many characters and not enough visual finesse, but that's really Kevin Smith's thing. Dogma is all about the characters, what they have to say and how they fit in to the complicated scheme of things. If you go with the flow, these apparent negatives soon melt away. Length: 125 minutes.

Verdict: Dogma is a rare treat - a hugely ambitious and funny film, patently from the heart. A late contender for comedy of the year.
