Love Actually
Love Actually gets a yearly celebration every time Christmas rolls around. However, if you remove the nostalgia blinders for a second, you can see that this movie lacks substance outside of its presentation. It's supposed to be a rom-com but it's neither particularly romantic nor particularly funny.
Traffic
The cinematography of Traffic almost completely overrides the plot. Even though lots of individuals think that it's a great movie, the most common criticism is that the plot fell flat while the camera-operators focused on the "fake set-up" that the drug traffickers were theoretically avoiding. The acting was pretty good, but good acting doesn't substitute for quality storytelling.
