Not a real musical
As of the 1940s musicals usually had a story that was punctuated by songs that moved the story along. The big breakthrough was supposedly Oklahama. This film does't qualify at all. It's as if they had to put The Greatest Hits of Abba on stage or film and come up with something to surround each song. Dancing Queen comes out of nowhere and then becomes an extravagant production number.
Do you think anyone in this movie was really singing or why they just going through the motions while a trained singer knocked it out. Actually watching James Bond pretend to sing was movie magic.
It's been so many years since I heard these ABBA songs...but after awhile not only do they all sound the same, they were arranged the same way too. After 4 lines of spoken words the music begins and repeats and repeats and repeats.
Had they just done a play called ABBA, and had actors dress up like the members of the band, go through some motions it might have been the same thing.
Ya got me.
