Idhu Namma Aalu would have been a crap if the director failed to cast Simbu and Nayanthara. This is a perfect example for a lazy writing that the director hasn't done anything other than writing counter dialogues for Simbu's real life love failures, his unpunctuality and several other imperfections of the actor. At one of time, this film appears like how Siddharth directed Bobby Simha in Jigarthanda, Pandiraj has literally made fun of Simbu's real life personality!
However the film is not a bearable crap, this one is actually watchable for the amazing chemistry oozes between Simbu and Nayanthara. Here, Soori is in full form that the whole theatre erupts whenever he digs at Simbu's love failure and his laziness, which is definitely entertaining.
In any love story, the lead pair must fall in love, then there should be a difference of opinion put them in splitsville for a while and then the film would end on a happy note. Idhu Namma Aalu is no different, so if you like such cliched execution, go and watch the film. Others you can have some good fun in the first half and also in the last fifteen minutes of the movie.
