After seeing such negative reviews i was pretty much sad.. But after seeing the movie it is not that bad..the transition between past and present is not that complex as critics say it is. The starting had some usleless and cringe scenes.The story line is also a bit sloppy. If you have very great expectation of the movie you may feel disappointed.
The acting and dedication of surya surely deserve praise and attention.
If you like action,rage , brutal violence and an overall mixed experience you should definitely watch kanguva.
