The Holiday [spoiler warning, heh]:
1. Jude Law's character receives a couple of calls on his cellphone while in the presence of his new-found love interest (Cameron Diaz) and she sees the caller IDs of "Sophie" and "Olivia" and gets sorta jealous. We later learn those are his two daughters (who are like 5-7?) spending the weekend at their grandparents'. Why in the world do those children have cellphones?
2. He doesn't answer for one of his daughter's call. Granted the grandparents might call if there was a serious problem...but ignoring the phone call of your young daughter for no good reason?
3. Jude Law has sex with Diaz in his sister's bed a couple of times and it's never even a thought that it might be inappropriate.
4. Kate Winslet, a mere journalist, got a last minute ticket to L.A. for the holidays...how?
5. Diaz got fed up with the loneliness of being in a small cottage in England after a day or two and was going to go back to L.A. when she could have headed for London or Paris and done anything. Plus where would that have left Winslet for the home exchange - would she have been allowed to stay?
6. Diaz's reviewed the movie trailer her team was creating and called for a couple of changes...yet it aired in England the next day.
7. The home exchange internet site appeared as a specialized program imbedded in the Desktop (in the shape of a house) which was ridiculous.
8. Diaz drove into town in the snow on narrow roads, confused and frustrated by having to drive on the wrong side. She then went into a market where she chugged a bottle of wine and presumably had to drive home in that condition.
9. Diaz had at least 3 different coats for her 2 week trip. And why did she bring a cocktail dress when she intended to be alone, delighted by the fact that there were "Zero" men in the town, according to Winslet?
10. Diaz's chauffeur refused to drive her all the way to the cottage because the lane was narrow and he wouldn't be able to turn around. Yet Law never has that issue in his SUV, nor does the chauffeur have that issue when he later picks her up and drives her back to the cottage when she has a change of heart.
