From my childhood I love suspense movies or serials. It was really a challenge for me and I used to guess the end of the episode. My brother and me always bet on it. CID is also a serial which increased our curiosity and force us to think. The real inteat of the serial and heart of the serial are ACP , Daya and Abhijeet. The coordination of these characters and intimacy is really creditable.
Which make audience to watch it. For so many years people are enjoing it. So watch the serial and scratch your head.
