There are some improvements here as co-writer and director Ol Parker limits the singing roles for some actors who struggled in the first film while allowing other actors to carry the bulk of the musical numbers. The flashback plot to Donna's original trip to Greece allows the casting of younger versions of all the characters in actors who are a bit more comfortable belting out the songs when called upon. Lily James is the stand-out as the younger Donna as the other actors look to have been primarily cast first for their physical likeness, second for their singing ability, and (unfortuantely) last for their ability to act.
