Whilst the film opened to rave reviews, Jiiva's portrayal as Prabhakar was praised by critics and widely termed as the best in 2007; a Behindwoods review labelled it as "a performance of his lifetime", while Rediff wrote that he was "endearing as the young, vulnerable Prabha, [...] perfect as the ganja-smoking near-lunatic [...] and freaking brilliant as the frustrated Tamil graduate". "He was, in a nutshell, simply superb". Jiiva had grown a full length beard for the character and cited the hardships during the shoots of the film, which he considered as his most painful experience and a "torturous affair".

Jiiva was a judge on STAR Vijay's reality dance competition Jodi Number One in its third season along with Sangeetha and Aishwarya Rajinikanth.
