Catching up on MAMA MIA!

Barely for the first time, MAMA MIA the film: enjoyed the abba songs, but the film is chronically flawed.
Meryl Streep did her thing and put on a great fight, but not even that could've convinced me to actually get into its world: the movie was too Stagy , prob since it is a straight port from the stage show. Not believable , the story absurd, and the way they transition into each song was like a cheap commercial gimmick.
I truly enjoy musicals, and there are far better stage show to film musicals out there Like HAIRSPRAY. But mama mia, it felt like a mediocre high school project
