'Sing 2' review: Fun animal musical sequel elevated by U2

'Sing 2' doesn't stray far from the formula, but still remains fresh thanks to some inspired laughs and a little U2.

Remember Sing, that 2016 animated movie about a bunch of animals, well, singing?

Its formula of likable and cute characters, big name voice actors and hugely popular, instantly recognisable pop songs was one that made over US$634mil (RM2.64bil) in the box office, which also automatically means that a sequel was inevitable.
