It's a Khichdi , to be honest. One scene plucked out of movie aparichit . Few scenes from Mersal and Gabbar. One scene from Batman Dark Knight etc etc.
For someone who had grown up watching srk movies like DDLJ, Swades, Veer Zara, Chak De etc , this was absolutely devoid of creativity.
Best part of Jawan are the scenes including individual stories like Dr Eeram, farmer's daughter etc. Talent of Vijay Sethu pathi performed well. Nayanthara is the surprise package in this movie. All in all, one time watch.
