Jamie (Colin Firth) and Aurelia (Lucia Moniz)'s storyline is classic romantic comedy stuff. They don't speak each other's language, but fall in love anyways.

2. Mark & Juliet
I dare you to find a straight women who didn't fall in love with Andrew Lincoln (Mark) after witnessing his "TO ME, YOU ARE PERFECT" scene. Their storyline starts off with Juliet (Keira Knightley) marrying Mark's best friend (Chiwetel Ejiofor). While it first appears Mark dislikes her, it turns out he's in love with her. Awwww!
3. Daniel & Sam
This story starts off sad with the funeral of Sam's mom and Daniel's wife. Daniel (Liam Neeson) is Sam (Thomas Sangster)'s step dad and the two bond when Daniel tries to help Sam win the heart of his dream girl. Probably the cutest of all stories.
4. Billy Mack & Joe
A funny storyline about an aging rocker (Bill Nighy) and his manager, trying to recapture their glory days by landing the Christmas #1 with the awful 'Christmas is All Around'.
5. David & Natalie
Hugh Grant is perfect as the Prime Minister who falls in love with employee Natalie (Martine McCutcheon).
6. Sarah & Karl
Sarah (Laura Linney) has been in love with Karl (Rodrigo Santoro), her colleague, approximately forever, but never had the guts to do something about it. When something finally happens, she lets him slip away. This is probably the saddest story of the bunch as it's the only one with an unhappy ending.
Colin (Kris Marshall) can't get a girlfriend in Britain so he decides to go the USA as he's convinced he'll be a chick magnet there. It's a funny storyline with cameos by Ivana Milicevic, Elisha Cuthbert, January Jones, Shannon Elizabeth and Denise Richards.
8. Harry & Karen
The only thing that saves this storyline is the awesome Alan Rickman. His Harry cheats on his wife Karen (Emma Thompson). It's rather depressing really.
9. John & Judy
This is supposed to be funny, but it doesn't really work for me. It's more gross out comedy, which the other stories tend to shy away from.
