Behindwoods wrote "Pandiraj is successful in showcasing the life of a community in its various facets which could be interesting to some. He has fused realism and cinematic elements in the right proportion and has sliced his way through the path less trodden with considerable aplomb this time also."^[4] Rediff wrote "Vamsam is an intriguing tale of the clash of clans, but it suffers from overkill."^[5]
