What went wrong with Jijaji2? These are my reasons which I could think of now.
1. Not giving prime time slot to a new show.
2. No promotion for weeks.
3. Some unclear promotions.
4. Love web plan track which could be avoided in a romcom show. Online dating was more suitable. They ended that track in 2-3 days but ran this bakwaas love web plan for so long. Though they frequently changed Jija's plan but some of his lines and acts were disgusting in that track.
5. Lack of JCP true friendship development scenes as they ran love web plan for long. The friendship developing scene ran for so less time from Jija saving CP from eve teaser episode till Holi. Instead of love web plan they should have shown their true friendship to develop.
6. After bhootni being trapped, showing leads parents fight again for house.
7. Leads parents being Anti-JCP for no reason.
8. Glorifying kidnapping for love though its not major reason.
9. Taking too long to make important characters know evil power's identity.
10. Not giving suitable promos every week like there should have been promos for Titli kidnapping and find her mission, Jija getting attacked by bhootni in her room and others reviving him, JCP bonding promo when Jija constantly consoled crying CP during Titli's kidnapping, Jija's feeling guilty for love web plan and true love realization promo, Jija saying away after bhootni's warning and CP's flirting promo(extension of that mini promo of CP in Jija's arms), misunderstanding pregnancy promo, Queen Emily diary about curse breaking and finding curse breaker promo, CP-Gullu love act and Jija's confession promo, CP confronting bhootni promo after knowing the truth from Jija, CP knowing Jija's love web plan promo and so on. If these promos were played every week in creative ways then show's ratings would have surely increased and show would be saved.
11. No song sequence used on scenes except Jaane Kaise in episode 51.
12. Little to no dance sequence of main characters especially family dance. They only showed it during Holi, Naag-Naagin track and JCP dance on Jo Tum Na Ho in garage. JCPH had many dance sequences and interesting tracks which Jijaji2 too should have done.
I could only think this much. You guys give other reasons😊.
