Story:

Guru (Sundeep Kishan), a Vizag-based youngster, runs a home library that was very close to his mother’s heart. However, he is burdened by a ₹1 crore debt left behind by his late father and is under immense pressure to clear it as soon as possible.

Things take an unexpected turn when Guru learns about a dangerous drug called Caesar, which is controlled by a gangster named Vincent. With crucial evidence related to Vincent’s illegal operations in his possession, Guru decides to blackmail him for money.

However, Guru soon discovers that Vincent is only a part of a much bigger network controlled by international smuggler Kotlapati Venkata Reddy (Sampath Raj).

Did Guru manage to get the money he desperately needs? How does he take on Vincent and Venkata Reddy? The rest of the film is about this conflict.

Performances:

Sundeep Kishan fails to make a strong impact in the lead role. The character lacks the style, energy and distinctiveness needed to elevate his performance, leaving him with very little scope to shine.

Faria Abdullah, Raju Sundaram, Sampath Raj and the rest of the cast also have limited scope and fail to leave a significant impression.

What Works:

Jason Sanjay picks a simple storyline that has the potential to become an engaging heist thriller. The basic premise has enough material for a fun and gripping ride if handled with a tight screenplay.

The interval episode provides a brief spark and creates some hope that the film might pick up in the second half.

What Doesn’t Work:

Unfortunately, Sigma feels outdated right from its opening scene. The film follows a routine narrative and an old-fashioned style of filmmaking that fails to suit this genre.

Heist thrillers demand a tightly written screenplay, but Sigma struggles badly in this department. Guru’s problems fail to create the desired emotional impact, while the romantic track with the heroine also feels flat and uninteresting.

Although the interval episode briefly raises expectations, the second half goes in a completely different direction. The narrative keeps moving aimlessly, with scenes appearing to unfold without a clear purpose.

The heist sequences involving Guru and his gang are particularly disappointing. Instead of generating tension or excitement, several scenes lack logic and come across as silly. There are far too many such moments throughout the film.

The repeated use of similar situations becomes irritating after a point, making the proceedings feel unnecessarily stretched. Even the climax turns farcical, failing to deliver the high or impact expected from a film of this genre.

Sigma Review And Verdict:

Sigma, directed by Jason Sanjay, has the basic ingredients to be an engaging heist thriller. However, weak writing, a loose screenplay, silly heist sequences and outdated execution completely dilute its potential.
