One life-threatening, story-aggregating episode follows another so that, long before the film ends, you wish Arthur and his chums would have a lie down.
While adults may well be fumbling for paracetamol after a few minutes, their offspring may well love its sugar-rush energy.
Even those generous enough to have rescued 2007's part-animated Arthur and the Invisibles from a DVD bargain bin would likely concede there wasn't much call for a sequel.
The narration is somewhat muddled, the special effects are almost endearingly naïve, and I cannot see who it's aimed at.
Luc Besson directs, with no apparent concern for logic or coherence.
