"Thrash" and "Barb" have discovered thanks to "Poppy" and "Branch" that it's not just rock that makes the music world tick in Troll land. They are not impressed, and so set about on a unification drive that will eliminate just about everything from techno to pop so that it's just their favourite music that prevails. "Poppy" gets wind of their not so cunning plan and they decide that they need to galvanise all Trollkind to thwart this regal plan. This sequel is a bit bland but still offers some perfectly watchable fayre to plonk the kids in front of on the television. Otherwise it's all just a bit lazily disappointing with a few ballads and mediocre AOR tracks peppered throughout a soundtrack that turns a battle of the genres into more of a limp skirmish. The animation looks pretty fake from start to finish and though there is actually the semblance of a story here, the characterisations are undercooked leaving us with something remarkably sterile - despite it's vibrancy. I'm not really the demographic, but Dreamworks seem to be determined here to capitalise on the brand and an awkwardly delivered mixed message about equality and individualism rather than create something remotely memorable or that might resonate with the younger audience above whose heads most of this will probably wash.
