I was a good husband and rented "Mamma Mia" for my wife last night since we watched "Hancock" the night before that. I don't mind the occasional chick flick or musical but I was hesitant to watch a movie version of a musical based on ABBA music. (Cringe.)
I consoled myself with the fact that Meryl Streep, Pierce Brosnan and the guy who played Obi-Wan Kenobi's Jedi Master in "The Phantom Menace" were in it and that they don't usually suck.
I've come to the conclusion that the reason I'm not a huge fan of musicals is this: I cannot suspend disbelief enough to accept that people are spontaneously bursting into song because they're in love, angry, horny or drunk.
Well, I guess I could believe it when someone is drunk.
I also get freaked out when they have a conversation in song and when bystanders in the crowd sing back-up (especially when they're "ahhhh, do wop, do wop" back-up singing). If someone started singing "sha doobie do-wop" when I was having an argument with my wife or singing about how much I love vanilla flavored Silk I would run screaming to the nearest psych ward.
I left the room periodically to preserve my sanity (and listen to something that wasn't ABBA) but thought that the movie was decent and that I won't be buying it anytime soon.
