Isai

Vetriselvan (Sathyaraj) is an established and old-fashioned music director who is loved and respected for his works and is termed as the greatest musician of our times. A. K. Shiva (S. J. Suryah), who works as an assistant under Vetriselvan, gets an opportunity to compose music for a small-time film. When Shiva introduces new techniques and pioneers the use of synthesizers, his music gets the attention of all music lovers. Due to the freshness and modernity that his music possesses, he becomes the most sought after musician and overtakes Vetriselvan. Shiva becomes the number one musician and builds his own studio. Meanwhile, he falls in love with Jeni (Sulagna Panigrahi) and marries her. When it seems everything he touches turns to gold, Vetriselvan displays his true psychopathic form.

Vetriselvan decides to pull down Shiva by any means. Vetriselvan wants to disturb Shiva's peace of mind so that he could not concentrate on music. Vetriselvan enters into a deal with Shiva's car driver, manager, cook, and studio front office staff to get their help in bringing down Shiva. One day, Shiva's car driver parks the car amidst peak traffic and suddenly runs away, which confuses Shiva. He gets disturbed by the continuous honking sound. Shiva's manager also confuses him by giving some fake incidents which did not happen. Jeni gets conceived but gets aborted as Shiva's cook mixes some medicine in her food. Shiva is worried because of Jeni's miscarriage and cries aloud. He thinks that he is mentally disordered and goes to a mental hospital.

Shiva's strange behavior gets the attention of media, and his image is tarnished amid public. Vetriselvan feels happy seeing this and in the meantime, film directors start approaching him again. Vetriselvan thinks that his lost glory is recovered now. Finally, it is revealed that Jeni is none other than Vetriselvan's daughter who was sent by him so that he can accomplish his plan. Knowing this, Shiva gets furious and comes to kill Jeni. But she reveals that she has really fallen in love with Shiva for his kindness and she is conceived again now. Vetriselvan comes there and persuades to kill Jeni knowing that she really loves Shiva. In the meantime, Vetriselvan stabs Shiva with a knife.

Suddenly, Shiva wakes up, and it is revealed that the entire story was his dream. Madhu (Nila) (from Anbe Aaruyire) is now his wife, and she says that fans are eagerly awaiting for a movie as he has not made a movie in the last 10 years. Shiva says that he got a story from his dream and needs to decide the climax. The movie ends there.

Suryah, not being confident to start his career as a composer, eventually shelved the project and later worked on Puli (2010) with Rahman joining as the composer.

After a two-year sabbatical, in November 2011, Suryah announced that he would revive Isai and would produce, direct and compose music for the film, having completed writing the new script. Describing it as a musical thriller, was supposed to be made as a bilingual in Tamil and Telugu languages but later stated that it would be made in Tamil. Describing the synopsis, Suryah stated that it is about the rivalry between two music directors—a leading veteran composer in the industry being replaced by his younger competitor, leading to the former becoming jealous; he further added "the situations in the film are what we come across in every field. We often find someone reigning supreme in one industry only to be eventually replaced by another. Isai deals with the emotional turmoil and the jealousy one who is pushed from a position of confidence experiences." Initially the film was produced by Victor Raj Pandian under the ASA Productions banner which was credited in the first look posters. but the company opted out due to financial problems and the project eventually took over by S.

The film received generally positive reviews from critics as well as from audiences. M. Suganth of The Times of India rated three out of five, summarizing "Isai isn’t as taut a thriller as Vaali but despite being overlong [...] it is fairly engaging. The film doesn’t truly come together as a whole but the scenes have the stamp of a director with a sure hand." Suganth however found the climatic twist "which neither feels organic nor ingenious", adding that "Suryah only seems to be acknowledging that he couldn’t come up with a satisfying end to the story he set originally out to film. All it does is give him a loophole to brush away the plot holes. Or, maybe, it his way of telling the whole world that SJ Suryah the director has literally woken up from his decade-long slumber." Anupama Subramanian of Deccan Chronicle gave three-and-a-half out of five and admitted that "Though most part of the screenplay is taut, at times it becomes predictable and drags. But post interval there’s never a dull moment and especially the last 30 minutes, it is director Suryah’s intelligently woven brave attempt that enthralls the audiences keeping them hooked to their seats."{{Cite web |last=Subramanian |first=Anupama |date=2 February 2015 |title=Movie review 'Isai': Suryah is back with bang! |url=https://www.deccanchronicle.com/150130/entertainment-movie-review/article/movie-review-isai-suryah-back-bang |url-status=live |archive-url=https://web.archive.org/web/20150209072323/https://www.deccanchronicle.com/150130/entertainment-movie-review/article/movie-review-isai-suryah-back-bang |archive-date=9 February 2015 |access-date=3 April 2025 |website=Deccan Chronicle}}

Baradwaj Rangan of The Hindu noted that the storyline "gradually becomes so preposterous that the sheer whatever-next factor pulls you through. After a point, the film lurches madly between psycho-thriller, Victorian melodrama (think Gaslight), horror-movie staples, and [...] a meta musing on the director's long absence from the screen and his return to it. Whatever else, you have to hand him points for audacity."{{Cite news |last=Rangan |first=Baradwaj |author-link=Baradwaj Rangan |date=30 January 2015 |title=Isai: Lots of problems, but the preposterous plot pulls you through |url=http://www.thehindu.com/features/cinema/cinema-reviews/isai-lots-of-problems-but-the-preposterous-plot-pulls-you-through/article6839653.ece |archive-url=https://web.archive.org/web/20160204215508/http://www.thehindu.com/features/cinema/cinema-reviews/isai-lots-of-problems-but-the-preposterous-plot-pulls-you-through/article6839653.ece |archive-date=4 February 2016 |access-date=3 January 2016 |work=The Hindu}} S.

Rakesh Reddy of Desimartini was critical of the three-hour long runtime and the lack of emotional connect but noted that the climactic sequence "stands out in the film".{{cite web |last=Reddy |first=Rakesh |date=8 February 2015 |title=Movie Review — Isai |url=http://www.desimartini.com/movies/isai/md2424.htm |url-status=dead |archive-url=https://web.archive.org/web/20150209065931/http://www.desimartini.com/movies/isai/md2424.htm |archive-date=9 February 2015 |access-date=9 February 2015 |website=Desimartini |publisher=}} In a negative review, Gauthaman Bhaskaran of Hindustan Times stated "Isai misses out on being a decent piece of work largely because Suryah could not resist the temptation to get into the frame, and was careless enough to litter it with illogicality—although the end might partly explain this. Even a captivating Sathyaraj cannot pull the picture out of the pit." Ananda Vikatan rated the film 43 out of 100.{{Cite web |date=2015-02-05 |title=இசை {{ndash}} சினிமா விமர்சனம் |url=https://www.vikatan.com/humour-and-satire/cinema/103404- |url-status=live |archive-url=https://archive.today/20250403145124/https://www.vikatan.com/humour-and-satire/cinema/103404- |archive-date=2025-04-03 |access-date=2025-04-03 |website=Ananda Vikatan |language=ta}}
