Scooby-Doo

'Scooby' the movie starts well, pitching itself somewhere between tribute and send-up of the Hanna-Barbera cartoon.

The casting is astute: best of all is Matthew Lillard as stoned slacker Shaggy.

Even the computer-generated Scooby himself isn't lacking in charm.

But 'Scooby-Doo' sadly fails to live up to the promise of its opening reel.

Admittedly, the film's bold playpen colours are fun and there are some clever gags that will score with the show's pothead following.

But the jokes soon wear thin.
