It would be great if they remain focused on story baseline. In season 4 if they show the characters from old season it would be best. They totally ignored some of the main characters from previous season. Bringing new character is though work and they failed in both 3rd and 4th season. Specially character Ani never suit the story as much as Antigo and other who came into focus in season 4. Otherwise 1 season and 2 season are fantastic I rate both season 9.8/10 and I rate Season3-7.8/10, Season4-6.8/10. The story they created was amazing but in story maintaining they totally failed.
