Somehow most of the people here reviewing did not seem to get the plot...THIS REVIEW IS REALLY SUITABLE FOR PEOPLE WHO HAVE SEEN THE FILM BUT FAIL TO UNDERSTAND THE ENDING.The pair divorced two years ago from the movie scene was simply because Mr. To knew he was sick and dying.He then let her enjoy her life a little and look for someone she could remarry.The fact that he stole the necklace in the end for her (in the help of the others), was because he wanted to give her hope that he was still somewhere watching her and caring about her, even though he was buried to the ground by then. This is how much love there is.This is a really romantic movie just like Jonnie To's "My Left Eye Sees Ghosts". If you have seen that one, you will easily get the emotion from this movie.

The movie despite of the usual HK cliché and its over the top extravaganza and major flaws in the storyline that does not make any sense at all.....yes despite of all these ... It is still one of my favorite romantic movie of all time.The main reason is because the love story. That even in today's society, where marriage are tangled in with prenup and the whole financial problems, with the lack of trust and the reluctant to let go to your own concept of the self and embrace the "we"....there are still certain romance that comes out of it. As ridiculous as the storyline of jewel thieves and millions dollar heirlooms, what essentially hit home to me is Andy Lau character, and his love for his wife. He knows of her competitive nature, he knows of her selfishness, her childishness, and he leverage that to pull the ultimate scam, to spare her the grieve when he's gone.For her it was the battle of wit, and she has always been holding a grudge because he's much smarter than her, and much wiser (for this I can totally understand, as someone who's competitive in nature and has fallen for someone who was much much wiser than I was) ... He always wins... And even in the end... He has successfully pull off the biggest lie. However, ultimately, he was always at the loosing end, he loves her so much that it doesn't matter if it's just a cheap ring, million dollar necklace, or all of his worth, he was willing to spend his time to entertain her with the cat and mouse game, and ultimately let her have everything, as long as they make her happy.The love story in combination of the classical guitar music and just the whole feel of the movie... I was ...for lack of a better word...touched by it all.

Plot summary: Sammi and Andy are a pair of successful thieves. Happily married, they've been stealing together since their teens. One day, as they were splitting up the gems, Andy suddenly announce he wants a divorce. Without an explanation, he leaves.To years later, you find a business tycoon named Steven proposing to Sammi but she only agrees if she is given a piece of the family jewels. But the sly soon to be mother-in-law doesn't trust Sammi and makes her agree to a contract. Sensing that this is going to be too much trouble, she decides to just steal the necklace herself. Only she is beaten to the punch by her ex husband. As she tries to recover the stolen necklace, the passions between the two are once again revived. However, one question will always remain: Why did he leave her two years ago? Not of a fan of either Sammi or Andy, I was pleasantly surprised to discovered that this movie was very enjoyable experience. The two lead characters had great chemistry together as they played very in-sync thieves as well as lovers. Although Andy is always a step ahead of Sammi, you can help but see that these two were made for each other. The supporting cast does their roles well. You feel sympathy for the blinded tycoon but know that Sammi is not for him. As well as the funny pair of comic relief detectives.Another notable aspect is the settings and the placement of all the characters. There are scenes that are like art displays. Nice camera angles and no lagging in the duration of the whole movie. The actors and plot line successfully pulls you in to a roller-coaster of emotions as you guess along with them what the other is thinking. With the benefit of knowing what the other is doing, the audience also gets to anticipate whether the other is aware. A fun puzzle like quiz. In the end, you will leave with a satisfied 98 minutes of delightful entertainment. Hope you like it as much as I did. =) something to look closely at: each time Andy gives Sammi a choice between two questions.

It wasn't the "perfect" movie. Take it for face value. The plot was good, but not super deep like something you'd expect from Wu Jian Dao (Infernal Affairs1/2/3), et all. It was light hearted and meant to get a few good laughs and entertain you - isn't that the purpose of a movie? Basically it's two people who are kleptomaniacs (people who are obsessed with stealing anything). Andy & Sammi give stellar performances. I've seen their previous two pairings under Johnnie To - Needing You & Love on a Diet - both of which were wonderful movies. Their chemistry is like that of Gregory Peck & Audrey Hepburn. Just.. something about it when they're on the silver screen seems to bring everything together. Well, as I pointed out before the plot's easy to follow. Basically they break up after a heist because of problems w/ the "distribution of assets" or so they say. Two years later she (Sammi) is about to marry some rich boy, but there's this necklace. Andy comes back out of nowhere to steal and so begins a little race (with plenty of pretty clever jokes) to figure out where the necklace is - and then some more.Enjoy it! Ended the movie with that nice-but-kinda-solemn feeling you got when you watched Roman Holiday. (haha) the box wasn't joking when they said it was a surprise twist :]P.S. still a little confused about the ending though. =___=
