They came, they saw, but sadly Britain's music critics largely failed to enjoy Tuesday night's revival of girl power at the world premiere of the Spice Girls' musical "Viva Forever!"

Reviewers panned a production loosely based on the band's meteoric rise to fame in the 1990s, complaining that its "charmless" script failed even as a basic invention for folding nostalgic pop hits into a West End stage show.

Independent newspaper critic Paul Taylor said the show "only achieves the kind of deliriously silly and joyous lift-off" at its encore and blamed scriptwriter Jennifer Saunders.

"Not only does her script rarely give you that necessary gleeful sense of expectancy about where the songs are going to be shoe-horned in, but it's embarrassingly derivative of 'Mamma Mia!' and looks way past its sell-by date in its utterly surprise-free satiric swipe at X Factor."

"Viva Forever!" was the brainchild of producer Judy Craymer, whose Mamma Mia! musical based on the hits of ABBA has earned nearly $2 billion worldwide and spawned a hit movie starring Meryl Streep.

She teamed up with British comedian Saunders of "Absolutely Fabulous" fame to create a story about the central character, Viva, a sprightly teenager who, along with her friends, gets into the final stages of a TV singing contest closely resembling Britain's "The X Factor".
