'Jimmy Neutron', the 'Rugrats' movies - children's channel Nickelodeon has provided some decent trips to the cinema in the last few years. But despite having a readymade audience for another afternoon out, Arnold's jump from little screen to big will leave frowns on more than a few faces.

Some may argue that the rough around the edges animation won't please the ever-fussier young punters, but the biggest problem here is the script. A 30-minute TV show is one thing, trying to stretch it over 75 takes a lot more work.

What you get here is the odd of hair, wide of face hero trying to save his neighbourhood from a property developer and calling on all his friends to get the job done. Admirable sentiments and plenty of nods to the value of history, community and teamwork but why not more laughs in between the lessons?

There are some nice plays on movies like 'Speed', 'Men in Black II' and 'All The President's Men' but Arnold & Co just don't deliver enough winks towards the adults or wows for the kids. And the fact that the finish is such fun shows just how saggy the rest of the movie is.

There's plenty of homework to be done between now and the sequel but Arnold fans can content themselves that whatever they have to knuckle down to won't be half as daunting a task as what's facing the makers of this disappointment.
