WOW! That was all I was thinking for the last few episodes with my mouth hanging open. I feel like every few months I stumble upon an awesome Japanese mystery/thriller that reminds me why i love this genre so much! Story: Refreshing new twist to an old plot line-a female villain?! Its usually a crazy male who is playing cat-and-mouse with the police and takes an interest in the lead during the investigation. In Siren, its completely reversed-its BECAUSE of the interest the villain (Kara Tachibana) takes in Yuki that the cat-and-mouse game begins. And boy what a game it is! But don't take anything at face-value because the ending will leave you scratching your head and surprised at where all of the twists lead you! Acting/Cast: Perfection! Let's be honest, without a good charismatic villain manipulating everything behind the scenes series in this genre would not be worth the watch. And Nanao as Kara Tachibana delivers crazy flawlessly (so much its scary!) I can't see any other actress pulling this role off as well as she did. As a matter of fact, there are other times and in flashbacks (which I won't speak of so as not to reveal any spoilers) when she is portrayed by another actress, but it falls short in comparison. And Matsuzaka Tori as Satomi was the perfect lead to play off of. Watching the two fight over Yuki for 9 episodes was a real chess match! Music: Don't look for an OST that you can sing along to, but the instrumental build up to some of the more shocking moments were well-placed, and the comedic moments were cute and well timed. Rewatch Value: A must. Especially the last few episodes when everything comes together and is being explained. I like to think of myself as a somewhat smart person, but I had to go back more than once to make sure I was following along without getting confused. Because the 'big reveal' at the end needs time to sink in and understand....And I'm still not quite sure I've got it all right!! Overall: Highly recommended to ANYONE! Its got the romance, thriller, mystery, action and so much more.
