I don't HAVE to have season 2, I think the drama is just perfect and complete as is. I don't see the ending as a cliffhanger, more just open-ended for us to complete ourselves. But of course I'll watch it if it comes out. Hope it'll be just as good as the first though. (Can that be possible??)
Why she became Chae all of sudden I have no idea - fixed the mistake.
The culprit still has not been arrested, so I hope they catch him. I wonder if he watched Signal and if he did, what was his reaction? He might have smiled thinking that drama is only a drama and that himself, the real culprit of the real life case would never be arrested.
The Inju rape case is based on the Miryang gang rape case from 2004.
The CW have created a remake of this series! Well kinda....not really. Its more a television of a 2000 film that has a similar premise to Signal, but if I had never heard of the film, I would have mistaken this show for an Americanized remake of a Korean show.
The casting for the Japanese show is pretty spot on, Atsuro Watabe (grey hair suit ), is usually pretty good, but Kazuki Kitamura (Kill Bill,Hojo Tokimune,Tenchijin and a slew of Miike films) is worth watching the series alone .He is one of those actors that can just lift a film or drama .
