Don't ask me, I can't resist it. Jessica and I saw it last night and now I want to buy the soundtrack (or ABBA cd or burn Jessica's), see the show in Vegas, and probably see this movie again.
If you like Moulin Rouge, Dreamgirls, Hairspray, or movies that are good- You'll love this.
p.s. I had no idea they sang "Take a chance on me". I mean I have only heard the Alvin and the Chipmunks version, so I just figured it was them that created it. I was obviously way off.
