In a follow-up to the Broadway sensation turned 2008 musical rom-com, Mamma Mia!, this film serves as both a sequel and a prequel to the original, flashing back to Donna's life before she was a mom (and before she met all of her potential suitors). Even with 10 years of anticipation, this film did not disappoint. As well as reacquainting fans with old faces, we were introduced to their younger equivalents, and all of the ABBA hits left out of the original got to make their film debut. Few movies are as pure fun and incredibly sweet as this one, so let's just say we wouldn't be opposed to a third instalment of Donna and Sophie's story.
