It’s Sad-Ism
Review by: Mirchi9.com
Critic ReviewRating: 4.5 / 10
First of all Kalyan Ram must be appreciating for going for a makeover. He changes not only his look but also alters his body language fitting the mannerisms of Puri Jagannadh. While all this is appreciable one must remember not all changes are good. Kalyan Ram never looks at ease with the “new” body language, his performance on screen comes across as trying way too hard.

Critic ReviewRating: 6.5 / 10
Kalyan Ram who has taken a breathable gap after Pataas has come up with some serious business at the Box Office. His six pack revelation made people go nuts about it and to be mentioned his performance was totally a ‘paisa vasool’ one.
This movie has good story plot

Critic ReviewRating: 7.0 / 10
This movie is going to make you excited and attract towards it. I think everything is good in this movie and the negative points are not going to affect the movie.
Over-dramatic and a not so engaging action film!

Critic ReviewRating: 4.5 / 10
The script offers mighty scope for Kalyan Ram to unleash his range as a performer. His daring, carefree and humor side have been portrayed pretty well in the first half as an illegal street fighter but it's evident that street fighting is just a mask and he has a back story. His character has few surprises that you will have to watch it for yourself at the theaters.
'ISM' Movie Review
Review by: IndiaGlitz.com
Critic ReviewRating: 6.0 / 10
A hero vs villain entertainer done on a template, and to cater to a section of escapism-lovers. Puri's fans will love the hero's characterization and dialogues. Kalyan Ram's best-ever performance. Outrage over black money is cinematic, impractical. A gripping screenplay around the hero's modus operandi would have helped. Action sequences should have been innovative. The climax works for many.
ISM – Message through technology

Critic ReviewRating: 6.5 / 10
ISM is a very honest attempt from Kalyan Ram and Puri. The Nandamuri hero’s stunning performance, first half, and a gripping pre-climax are major assets. If you ignore the lackluster climax and some hurried up scenes here and there, ISM will surely impress those who love hardcore commercial entertainers with a good message.
Too many Leaks in this!

Ism is an example for lazy writing and cliched treatment disguised as a clever and sensational plot.With its strengths such as hard hitting dialogues in climax.
