I have one friend who's very expert in rigveda , he says Raam never existed and curses Ramayan and his author over the villain-ization of Indra. Indra in rig veda is one of the most prominent gods , but in Puranas he runs around haplessly , often having his heavenly position snatched by the demons , and everytime vishnu rescues him. Whereas in vedas , indra "orders" vishnu.
My rigvedic friend didn't like it , and he claims modern day hinduism has NOTHING to do with vedas at all. That puranas are incredibly anti-vedic in their tone and that the krishna in mahabharat is essentially what is indra in rig veda.
Beware of hindu nationalists though who try to make their scriptures sound older than what they really are.
