Yennai Arindhaal is Goutham Menon's third outing in his sequence of cop films after Kaaka Kaaka and Vettaiyadu Vilaiyadu. Characterizations too traverse along the same path as those previous films like Jyothika as a divorcee with a child is replaced by Trisha as Hemanika. Protagonist proposes to Trisha and dialogues about raising Trisha's child throws light on upper middle class family's mindset and approval was given by baby Anikha with her emotions. Her emotions speak a lot in some of the well scripted scenes and montage sequences in the song unakenna venum sollu and Idhayathai Edho ondru.
Performance wise Ajith as Sathya dev traverse from 13 year boy, gangster, tough cop to caring father and it's Ajith show throughout the film. Another strong character is movie's antagonist Arun Vijay who enters large screen after a long hiatus and makes us awestruck with his performance and characterization too strong similar to Kaaka Kaaka's Pandiyan. Both leading actress Trisha and Anushka looks ravishing and marks their presence in short memorable characters. Another good thing in Goutham Vasudev menon's movies is portrayal of women and most of his women characters will be independent and practical. Grace and elegance of the heroines in Menon movies is accentuated mainly by their appealing costumes designed by Anu vardhan. Vivek evokes laughter with his one liners without interrupting the pace of the movie.
Screenplay is lethargic in first half and jam packed in second half. Some well made action sequences like climax chase between Arun Vijay and Ajith, while Ajith reveals himself as cop in the first half is highlight. On the technical side movie has brilliant cinematography by Dan Macarthur and picturization of Unakenna Venum Sollu is highlight among the songs. Maya Bazzar picturisation is little disappointment as dubstep portion in the song is removed and transition also not smooth. BGM by Harris Jayaraj with screeching guitars and drums is commendable although in action sequences sounds are bit jarring.
Overall Yennai Arindhaal is good watch for Ajith's and Arun Vijay's performances although director gave predictable treatment similar to his previous movies.
