2.0 VFX are truly to the expectations. Simply extravagant. Both stars have played their role well. Considering the superstardom of Rajnikant, Pakshi Rajan (Akshay Kumar) played villain character very profoundly. Movie had convincing backdrop of the modern era problem of birds getting extinct from our cities due to mobile radiation. Chitti reloaded was brought up nicely.
The negative aura controlling mobile phones was bit confusing between super natural or technology. Final fight between chitti and Pakshi Rajan in sports arena had amazing VFX but somehow missed the thrill from Robot and looked like a scene from Transformers.
Overall it another great movie from Shankar. 4 out of 5.
