Last Christmas

Plot hole: Kate goes to Tom's flat (the scene where they sit on the floor, she shows him her scar, and then he puts her on the bed). But as she obviously doesn't have a key to his flat and he (spoiler alert) isn't really there, she would not have been able to get into the flat.

Mistakes

Factual error: The family supposedly left Ex-Yugoslavia (what part isn't made clear exactly) "because of the war", but the only conflict still going on there in 1999 (when the family is still there in the opening scene) was the NATO bombing of targets in Serbia in order to get the Serbs to lay off Kosovo, and that was long over by Christmas of that year.
