The film opened in January 2000 to predominantly positive reviews from critics.
The Hindu gave the film a favourable review, remarking that "Vijaykanth excels in comedy and Ramesh Kanna has all the makings of a good comedian", "S. N. Lakshmi as the grandmother is hilarious and adds levity to the film as a whole" and that "Prabhu Deva and Kousalya form an energetic, sprightly pair." The critic also noted that "sentiment and sibling love fail to appeal after a point, when they reach implausible levels". Tamil magazine
Ananda Vikatan in its review mentioned "The film highlights the theme of everyone living with unity without any troubles [..] The drawback in this [..] film is there is no villain to the hero character and hence after some time the film struggles to hold attention without any twists".
New Straits Times wrote "This movie will appeal to those who love family dramas, especially about brotherly love". Ayyappa Prasad of
Screen noted "Vikraman, who is known for his deft screenplay and story line, has once again created a family entertainer which pulls at your heart strings and brings out the best of Vijayakanth in a dual role."
Vaanathaippola subsequently went on to become the most commercially successful Tamil film of the year, running for over 250 days in cinemas. The film secured a hit for the team and prompted Vijayakanth to star in further films. The film went on to win the
National Film Award for Best Popular Film Providing Wholesome Entertainment the following year. Furthermore, the success of the film led to two
Tamil Nadu State Film Awards, winning
Best Film for Ravichandran and
Best Director for Vikraman. In 2009, Vikraman and Vijayakanth came back together to make another family drama film titled
Mariyadhai, though failed to replicate the success of
Vaanathaippola. == Remakes ==
