Agreed: Show has a lot of mistakes, is sometimes VERY BORING, feels stretched out. BUT The characters of this show, their character development, their emotions, and specially the cast's performances are PERFECT. You can feel what they are going through, what in the past has happened to them and here the show shines the most. I don't know why people didn't like the ending of this show. After everything they went, the end was SATISFACTORY. This show is not at all sugar coated. The pain of all the characters remain with you for a LOOOONG time. This makes the show a very special one. The one thing I personally didn't like about the show is why do they have to redeem THE DEAD. The creators did that just to make more money and stretch the show out. This show is good or OkOk in all the aspects SEASON 1 was nail biting. Totally worth your time (8.9/10) SEASON 2 is the most boring thing I've ever experienced (though it gets right at some aspects) (6.1/10) SEASON 3 turned this show into a physiological thriller. A BAD ONE (4.9/10) SEASON 4 was a perfect end (7.7/10) Hope you find this helpful
