The storyline of the series took a twenty-year leap in January 2004.
In March 2004, lead Mouli Ganguly quit the series stating monotonicity.
The show opened with a low rating of 2.2 TVR in its debut week. But it saw a decline in ratings at its prime slot of 8:00 pm (IST) and thus that slot was taken by Kasautii Zindagii Kay in October 2001 while Kaahin shifted to a late night slot of 11.00 pm (IST). The decision was in show's favor as it became the first show to rake at good ratings ranging more than 5 TVR in that slot, also entering top ten weekly list of most watched Indian programs, which was before considered as a dead slot. In week 45 of 2002, it was at seventh position with 5.94 TVR. However, in September 2003, it was pushed to 11:30 pm (IST) slot after which the ratings of the series decreased the following weeks, garnering 3.4, 3.1 and 2.7 TVR during the following three weeks. Later, it settled down between 3.5 and 4 TVR.
India Today stated Sudha Chandran's role Ramola Sikand being one of the ideal vamps of Indian television.
