My first mythological series was Sir B.R Chopra's Mahabharat!
Then Ramanand Sagar's The Ramayana and Sri Krishna and Luv Kush.
then again the b.r chopra creation, vishnu puran
then Jay Hanuman and om namah shivay
then they only arabian mythology alif laila
next comes to mahima shani dev ki
after that Devon ki dev... mahadev
and now shows like siya ki raam, suryaputra karn, sankat mochan mahabali hanuman, shani and mahakaali.
My Favorites:
1. Devon ki Dev... Mahadedv
2. Ramanand Sagar's Ramayana
3. B.R. Chopra's Mahabharat
4. Karmfaldata Shani
5. Suryaputra karn
6. Mahakaali
The first three are from classic age and the last three are from modern age. The classic shows had a good and unspoiled core stories which i did not find in todays' shows. almost all modern mythologies have significant story manipulation which at times become misleading!
Again the modern shows are doing good in terms of technical sides like special effects and grandeur of the sets.
