i think what really killed this movie was

using that style , dont know what it is called, where you dont see all of the scenes in order. later, they tie them together and you figure it out. like when the girl called her friend to ask for a code, then later you see the girl trapped in the panic room and you find out she was the one who called for the code and it was for the panic room.
that style is very difficult to pull off. i think "lock stock and two smoking barrels" was one of the very few that got it right. the guy in the middle of the road with the tea cozy on his head was very funny, once you saw it all tied together.
but in this movie, we see guys run past the four girls, collide with them, lose something, look for it, and then run off when the cops show up. i thought the stolen diamonds were dropped into one of their purses, but then we see the pringles can. we also see the brother of one of the girls get a pouch, that looks like diamonds, to hold. then he gives it back to the guys who gave it to him.later we see the one girl get attacked by a woman looking for the pringles and we see the girl find the pringles in the street. I got dizzy.
i did not catch the abortion or the American girl being in Britain because her mother married a Briton. I was just trying to catch up.
I didnt even catch that an American girl and a British girl were sisters living in the same house. didnt notice accents. I was just too dizzy.
