ISM, in short, is a solid action entertainer that provides 2 hours of complete entertainment with both style and substance. The action is really outstanding, most notably the bike chase which stands out due to its camera angles and choreography, and is pretty much one of the best bike chases I have ever seen. The plot has a powerful message and one can easily relate to it.
Kalyan Ram looks really stylish and equally delivers on the performance front. The court scene, which has been praised by many, is indeed one of the biggest highlights of the film. His expressions in that scene along with dialogue delivery make it a larger than life experience. And of course, he impresses in action sequences as usual. Jagapathi Babu is also impressive as the antagonist, along with Posani Krishna Murali and other villains. Tanikella Bharani is excellent as always. Aditi Arya is fine.
The soundtrack by Anup Rubens is really charming and melodious (my copy of the audio CD came just today!). The production values are grand and spectacular. Editing is top notch.
ISM is an impressive action film that provides both entertainment and message, and that too in a proper manner. If you like action movies and are a fan of Puri Jagannadh/Kalyan Ram, you need to see this ASAP!
