Mamma Mia! Abba is great, musicals...not so much

The movie "Mamma Mia" was on T.V tonight I finally watched it, after many glowing recommendations and astounded "What! You haven't seen Mamma Mia??" from people.
I didn't like it as much as I had anticipated but that's probably because people built it up so much that it didn't have anywhere to go but down.
I love Abba. I grew up with their music and I love their songs, especially Chiquitita, which was not featured in the movie.
I also like the actors in "Mamma Mia", especially Colin Firth and Meryl Streep. It was a treat to see Colin Firth dressed in a 70's Abba costume singing alongside Pierce Brosnan and Stellan Skarsgård. I always like it when an actor who always does dramatic movies takes on a completely different role, especially when they do it really well.
I just cannot embrace musicals though. Much as I love Abba, I prefer to listen to their music separately and see a movie separately. Music is music and film is film, and for me it doesn't click well when they mix. I always sit there and expect them, or dread to be more accurate, to burst into song at any moment, which they always do when you least expect them to.
It rubs me the wrong way when a character is peeling a potato one minute and then suddenly burst out into song. That didn't actually happen in "Mamma Mia" but it's an example of the kind of things that you can expect in musicals. I know that the characters are expressing themselves through music but for me it's just an annoyance. When I realize that another song is coming on I let out a deep sigh inside and wish they would just get on with it. Here you have a dramatic moment and you're dying to find out what happens next in the story, and suddenly they start singing and dancing for 5 minutes straight.
When it comes to movies, I'm all about speaking dialogue. I don't mind music in movies, as long as it's in the background and not being sung out by the characters. In "Mamma Mia" the songs sometimes came almost back to back, and even though it is a musical, I didn't expect that.
It was an enjoyable movie though, even though I was disappointed that we never get to find out which one of the three men is Sophie's father.
Also, I have to say, I prefer Abba being sung by Abba and no one else. There's just something about the sound of them. Brings back fond memories of childhood.
Clogs, Abba posters and Agneta's long, blond hair which I always envied.
