Very fine acting by both leads but the final act's "twist" is quite terrible if you think about it. It requires a TEN MINUTE exposition DUMP to explain why it is a twist. After you receive the dump it makes sense why she did it but...( Spoiler ) how did she match with him in the dating website?? Her plan has no flaws and no real hints to what she is really doing. Which it is why it is a bad twist. A good twist gives you clues or something that you will miss on the first watch but then understand thinking through it. A good example is shutter island, if you watched the movie you know what I mean. Overall its goodish film. Watch it if you want to. But if you have to opportunity to watch shutter island defiantly watch it instead of this.
