most love stories are easy to understand, eg. how to lose a guy in 10 days, you can understand it very well in spite of the noise from the airplane ;) ;
war theme is a bit hard, involving those daily words but have totally different meaning in battle field~~~;
historical is mostly in old British English, like Brave Heart
kids movies are quite good, in terms of understanding, and humor
bear in mind:
the more you watched, the more good movies you will get and the more accents, and difficulties you will encounter~~~
yes. i love discovery, national geographic a looooot, but seldom watch animal planet~~~ :D
