Before we start writing the review, we can clearly make an understanding, that director Siva tries to make a Viswasam with Rajini and he fails with an outdated 90s script and screenplay. However, Rajini being the only saving grace has lifted the movie and carried all the way and Keerthy Suresh's emotional scenes might work in B and C centers.
In Soorakottai, Kaalaiyan (Rajinikanth) is a nice samaritan whose life revolves on his sister Thanga Meenatchi (Keerthy Suresh). Kaalaiyan wishes for his sister to marry in a nearby village, but most possible partnerships respectfully decline the offer, believing that his shallow love for his sister will negatively impair the marriage life. Finally, Kaaliyan's adversary (Prakash Raj) is inspired by Kaaliyan's compassionate heart and announces his desire to arrange the wedding of his brother and Thanga Meenatchi! Thanga Meenatchi goes missing just as Kaalaiyan is preparing for the grand wedding, and the first part ends on a cliffhanger. The rest of the movie is about Keerthy's journey to Kolkata. How Kaalayan saves Keerthy from the villains and why she lost the money forms the rest of the story.
Annaatthe's first part moves at a leisurely pace, with shimmery brother-sister feeling and unnecessary comic bits starring Khushbu, Meena, Sathish, Soori, and many others. As the lawyer, Nayanthara looks stunning and regal, but she has almost nothing to do, and it's Rajinikanth all the time. Keerthy
suresh is sincere, yet, as previously stated, too much melodrama detracts from the novelty value. Rajinikanth appears to be extremely intelligent and youthful, and his dialogue presentation, nonverbal cues, and
comedy lines are all a joy to watch.

Imman who scored with Kanaana Kanne song in 'Viswasam' fails to repeat the magic again in 'Annaatthe' and the sister sentiment song is no match for 'Kanaana Kanne' despite Chitra amma sang it. Overall, Annaatthe is Tried and Tested Rajini Formula and it entertains and don't expect a Viswasam!
