infernal affairs - the trilogy

I love the first movie, so much so, that I hesitated to watch the subsequent movies made after it, because I didn't think it would live up to the original. And they don't. But they do provide a lot of backstory and add a bunch of depth to the characters, and deepen the theme of the unending Buddhist hell referenced by the Chinese title. 

I will write a bit more about it later, but I just wanted to note one part in the 3rd movie where a character, who has her computer stolen, says this line of dialogue to the other character who definitely stole the computer but she doesn't suspect him at all: "It's ok. It's of no use to the thieves anyway. They would never have guessed that my password is my license plate number", while looking at a picture of her car with her license plate very prominently displayed. 

It was such a stupid thing they shoehorned into an otherwise fine movie.
