Same here... Agantuk was the first ever ITV ML that I loved. And because of him only I watched DKDM...
I watched it mainly for the love story of Sati and Shiva. My brother loooooves mythology and I still have a habit of following his favorite shows. I think DKDM was the first Indian show with proper VFX. I noticed much later that Mohit Raina played Agantuk. Or I might have seen GKD when I was in 1st/2nd year while DKDM - I started when I was in 11th standard.
Only a few episodes...
But I am planning to watch it during my vacations when my exams get over...
You should! It's amazing. Are you sitting for 12th's board exam?
