Query: Worst - Movie - Ever!!

If it wasn't for a bet that I had going with a friend, I never would have spent the $3.50 to buy this movie. It was simply awful! I understand the story line and that it's meant to be a comedy, but please don't show this to young girls as they may get the wrong idea. I think giving it an "R" rating will help ensure that young, impressionable girls WON'T see this movie. The only two funny scenes in the entire movie are when Muriel and Rhonda are on vacation and singing Waterloo in a talent show, and when Muriel is walking down the isle to get married, and the song "I Do" is playing as her wedding march. Seemed fitting.Recap: Don't waste your money.As for the bet - Which movie better represent Abba music. Mama Mia wins by a landslide!
