Love Actually
A pleasant movie where you don't feel time passing. Even though it has some minor flaws, it's a very well-rounded movie that includes several different stories, while never becoming confusing or hard to follow. It's a simple, accessible, and good-quality movie, but above all else it achieves its goal: to entertain the viewer.
PS: I will never forgive Alan Rickman for gifting the necklace to Heike Makatsch instead of Emma Thompson.
