As an IT techie, Simbhu leads a happy-go-lucky life along with his relative Soori. His parents, in a bid to get him settled, starts looking out for alliance and that's when they come across Nayanthara's family. When things go smoothly, the elders plan to get them married off and the pair gets engaged.
The duo gets in touch with each other through long duration phone calls and in one instance, Simbu confesses to Nayanthara that he was in a relationship before with Andrea and since things didn't work out, they broke up. Meanwhile, an incident between the lead's fathers, Jayaprakash and Uday Mahesh end up badly and it leads to a tussle among the families.
Whether Nayanthara got over the fact of Simbu's previous relationship and if the families sort out the difference in-between them to get the marriage done as planned forms the crux of Idhu Namma Aalu.
As a techie guy, Simbu has underplayed his usual larger than life persona that he likes to portray mostly. His simple acting and casual dialogue delivery is interesting to watch. Nayanthara shines as a beautiful family girl. Though her character makes her explore a number of emotions in the first half, she mellows down as a girl in love after she falls for the hero.
Soori as the jobless sidekick of Simbu takes away the agony of watching the lead talk for hours on the phone. His counter dialogues in between them conversing is a highlight and he travels throughout the film with Simbu.
Andrea, though coming only in the flashback scenes, looks pleasing in her role. The rest of the cast have done a commendable job with their characters.
After taking films with kids, Pandiraj has experimented in taking a love subject with youngsters and from the looks of it, he has done it successfully. His dialogues are a major plus point for the film. Though the conversation between the leads to end up boring and tiring at times, some dialogues, along with Soori's comeback dialogues makes it watchable.
Kuralarasan's music is pretty good. He has scored well with the background music and the songs along with its picturization is a treat to the audience. The song which has Simbu shake his leg with Adah Sharma will make those watching the film dance along. KT Balasubramaniem's cinematography makes the film look colorful and enjoyable.
Overall, Idhu Namma Aalu is yet another clean entertainer from Pandiraj that's worth a watch.
