i agree with the poster before that the character be exceptionally strong and believable and all the actor at their top form . i especially love david boreanaz stretch in a part so unlike anything else he play prove once again his amazing gift for comedy . the first part of the movie be light and funny and the blackmail part be a bit surrealistic but interesting and it be all downhill from there . i find it frustrate that at least two out of the 3 girl ( keira and lisa ) get out of the blackmail and betrayal scot free and nary a trace leave on their psyche . i know the movie amend the darker end of the play and i be not say i miss the murder part . but i surely need to see those two get their comeuppance somehow and i be leave groaning in frustration with the end . ( it why i give it only a 9 ) but definitely an interesting film .
