* SugarWiki/AwesomeMusic:
** Creator/MerylStreep actually won an award for [[http://www.youtube.com/watch?v=_0mgC4fivoI her rendition]] of "Mamma Mia".
** She also did "The Winner Takes It All" in one take.
* EndingFatigue: There are three musical numbers after the plot is wrapped up, plus the first portion of the end credits has two more songs. Amusingly, this opened in the U.S. the same day as ''Film/TheDarkKnight'', which also had trouble wrapping up.
** The stage version ends this way as well, but "Take a Chance On Me" occurs ''before'' the wedding, and "When All is Said and Done" doesn't occur at all.
* EnsembleDarkhorse: Epic Stick Lady during "Dancing Queen".
* FamilyUnfriendlyAesop: Sleep with three guys and don't know which is your baby's father? No, don't take a paternity test, wait decades and have fun singing about it.
** DNA tests didn't exist in the 70s, when she got pregnant. They could only do a blood type match, and if any of the men shared a common one (or Sophie had the same one as her mother) it wouldn't tell them who her father was. The question was sidestepped in the film version, where one of the fathers says they could get a test done, but they didn't really need to know.
* FridgeBrilliance:
** Anyone familiar with genetics is capable of guessing that [[spoiler: Bill]] is Sophie's father, as confirmed by WordOfGod, because he's the only blond of Sophie's three possible fathers. As blond hair is a recessive trait which Sophie shares with her mother, the other two would be pretty unlikely.
** It's also implied that Donna might be lying about not knowing who Sophie's actual father was, since [[spoiler:Bill]] commented that he thought his great-aunt who Donna had taken care of before she died had left her money to family. [[spoiler:Because, of course, she ''did''.]] It seems rather unlikely that the great-aunt at least didn't figure it out eventually, though Donna might have been in denial. Of course, whether Donna would be in a situation to find out about the recessive trait of blonde hair is up for grabs as well.
** The thing about genetics and blonde hair being a recessive trait is as good as irrelevant, seeing as how plenty of brunette parents have blonde children, and [[spoiler: that Stellan Skarsgård's]] hair is naturally brown, but has lightened with age.
* GermansLoveDavidHasselhoff: Due to premiering on the same day as ''The Dark Knight'' it wasn't as big a success as it should have been. However, it did extremely well in Europe (where superhero movies aren't that popular), and at the time of its release was the highest grossing movie ever in the United Kingdom. It currently sits at sixth.
** Actually, releasing it on the same day as ''Film/TheDarkKnight'' (as counterprogramming) was an intentional choice, and may have even ''helped'' its success. It made $144 million in the US, which is huge for a musical chick flick. Moulin Rouge, for example, was considered a success at $57 million. Of course, its ridiculous foreign gross still means that its an example of this trope.
** Not to mention it actually ''did'' outgross ''Film/{{Avatar}}'' in ABBA's native country, Sweden.
* NarmCharm: The ladies in full getup after the movie's fully over? Alright, you can take that with a giggle or two. But when the GUYS come out in costume for "Waterloo"? Oh dear God.
* [[HeReallyCanAct She Really Can Sing]]: Creator/AmandaSeyfried surprised a lot of people. In fact, one of the reasons she was cast was because she could pull off a high note during "I Have a Dream" ("I believe in angels..."). Her performance here would later be heavily credited for earning her the role of Cosette in the film adaptation of ''Theatre/LesMiserables'' four years later.
* TheScrappy: For many people, Skye's controlling personality and constant whining, while also being probably the least entertaining personality in the movie, helps him qualify for this position.
** For others, this 'honour' goes to Sophie, for her utter stupid plan in order to determine who her father is, so he can walk her down the aisle... which not only ends up going nowhere, but it's rendered useless TWICE by Sophie herself, first with her asking her mother to walk her instead and then by deciding not to get married at all. For those people, Skye's frustration with Sophie, who's shown herself to be an arrogant, self-involved dimwit, id perfectly understandable.
* SugarWiki/RuleOfSeanConnery: For many viewers, Meryl Streep's presence - and acting skills - transform the movie from merely barely tolerable to actually quite enjoyable, provided much WillingSuspensionOfDisbelief is applied.
* SoBadItsGood: Creator/PierceBrosnan's singing.
** Lay All Your Love on Me and Does Your Mother Know? are also entertainingly cheesy scenes.
** Creator/MarkKermode highlighted this in [[https://www.youtube.com/watch?v=61UolzFTVPI his review]]. He claimed that it was so utterly 'head-between-the-knees' terrible that he actually ''enjoyed'' it.
* TearJerker: ''Two'' moments right in succession: Donna singing ''Slipping Through My Fingers'' while getting Sophie ready for the wedding and ''The Winner Takes It All'' sung by Donna to Sam a few moments later.
* WTHCastingAgency:
** So, what is Creator/MerylStreep doing in a musical? [[SoMyKidsCanWatch She went to see the stage show with her daughter for her eleventh birthday and got kinda hooked on the idea.]] Also, one critic commented once on how she keeps touching her face and using her expressions mostly for acting, which makes it seem as if she's just a head. One journalist in Israel asked her if she was trying to prove she has a body as well, and Streep replied this might have been the case.
** Better example would be Creator/PierceBrosnan. Clearly he was cast to be swooned over rather than listened to.
