Trip into world of musical mayhem COASTER

the rock trolls, decides to unite them under one rhythm, the cuddle-mad Queen Poppy of the pop trolls decides to kill her plans with kindness.

The message here is about respecting cultural differences, which should strike a chord with parents.

But there are so many trolls and so many tunes, there’s no room for the salty back and forth between the leads that provided the biggest laughs in the original adventure.

Thankfully, Poppy, Branch and James Corden’s Biggie go down some amusing byroads on the way to the slightly preachy finale. Sam Rockwell raises chuckles as a wandering cowboy who rustles up memories of Lee Marvin with a croaky cover of Patsy Cline’s I Fall To Pieces.

But Jamie Dornan nearly steals the show as a sinister “smooth jazz troll” who tranquillises his victims with laid-back beats.

This loud, garish and fitfully funny adventure isn’t a film to relax to. Still, if it exhausts the kids, it could be £15.99 well spent.
