Movie musicals are a difficult genre to bring to life, first of all. Taking all the stage actions and turning them into something bigger, more visible, and more "real" is hard. The singing of the older actors, particularly Brosnan and Streep, was not Broadway worthy but worked in the contexts of this movie. Brosnan seemed to struggle with the "singing" on screen, but Meryl Streep did a wonderful job of emoting the songs, being pained, loving, being loved, being angry, etc. The younger actors were definitely more prepared and probably more experience in musicals but it didn't necessarily give them an edge acting wise, but vocally there was a major difference. The goal of this movie is to tell a story through song, and it did it wonderfully. I would not, however, buy the soundtrack. I would see the stage production or buy the original cast recording after seeing this movie. So, not a huge loss! P.S. I actually loved this movie. LoL. Personal is 5/5.
