I have no idea why there are so many negetive reviews about the film. I watched it in 3D and it was pretty good. The VFX and BGM are top notch, there is a good storyline and especially the action scenes were splendid. I would say the major drawback as the love story between shiva and isha.
Definitely give it a try watching it in 3D only, 2D might not make you feel the graphics appealing.
