There's life in the old god yet...

Billed by star Chris Hemsworth as Thor's masculinity crisis - single, less hair, loss of lump hammer leading to performance anxiety - Ragnarok is the best of his three solo outings and repositions Mr Odinson closer to Guardians of the Galaxy than The Avengers.

With Hunt for the Wilderpeople helmer Taika Waititi behind the lens, it's a more-ham-and-cheese masterstroke that gives the elbow to the Shakespearian spouting and makes comedy charm the key to its thundering success.

And so Thor throws together a motley crew of loyalty-phobe brother Loki (Tom Hiddleston), a sulky Hulk-turned-up-to-ninety Bruce Banner (Mark Ruffalo) and an on-the-pop warrior, Valkyrie (Tessa Thompson), whose rallying cry has become 'whatever'. From cameos to Easter eggs to movie nods, there's loads of delights along the way - don't spoil the surprises for other mere mortals.

Brothers in folded arms - Thor and Loki bring mirth along with the mayhem

Once again, the plot is the 'we're all doomed!' wheeze with Thor's home of Asgard geared up for the galactic glue factory at the hands/nails of Cate Blanchett's Hela - Cruella DeVil with way better dress sense and snarkiness.

Tessa Thompson is good, but underused as Valkyrie

Brighter and brasher than its predecessors, Ragnarok has that age-reversing allure that gives the same kind of high as when you first had your paws on the pages of comics way back when. It works equally well as a kids' gateway to all things superhero as it does at giving characters and veteran viewers a shot in the funny bone. Spare a thought for the in-costume cast having to keep a straight face.

Hulk is ready for his close-up

The ending is a bit Marvel cookie cutter (again) and there was more comedy to be had in a clumsy Thor-Valkyrie courtship, but as the warm-up act for next year's Avengers: Infinity War, the Ragnarok gang leave the crowd in much better shape than they found them.

Great double act chemistry between Chris Hemsworth and Mark Ruffalo

Another show is well in (Th)order.
