Bad guys are after two rings that contain the entire Witness Relocation Programme, so the angels (Diaz, Barrymore, Liu) and their minder Bosley (Mac) go undercover to get them back. This involves such adventures as a Mongolian rescue, a day of surfing, an off-road motorbike race and a Hollywood movie premiere. All while battling an angry former angel (Moore), a mysterious thin man (Glover) and a nasty Irish gangster (Theroux). Oh, and juggling their personal lives.

If you enjoyed the first film, you know you have to see this. It's jammed with hysterically funny bits -- subtle plays on the original 1970s TV series, inspired comedy, rude innuendo and outrageous goofiness. Diaz, Barrymore and Liu have taken the roles to heart; they make us laugh with every ridiculous disguise, gleeful wiggle and knowing line of dialog. Diaz is the star this time, with those gob-smacking guises and incredibly happy feet. And Moore makes a terrific nemesis -- sexy, nasty, energetic. Mac struggles a bit as Bosley, admittedly a thankless role in which he's only given weak shtick but still generates chemistry with our heroic trio. And McG directs with the same inspired flair, never letting up for a moment and brilliantly layering the comedy with satire, pastiche and childishness.

It's perfectly structured to keep us laughing in every scene, with regular forays into over-the-top action so intense that it's simply bliss to watch. The effects are ropey and far-fetched; there's no attempt to make anything realistic, so think of it as a cartoon! And star-spotters will have a field day keeping track of the witty cameos and bizarre supporting roles. OK, this is a love it or hate it movie, but if you thought the first one was divine, this more than lives up to expectations, which is something you can't often say. And while I wait for a third film (please, girls!), I'll be placing an advance order for this one on DVD.
