'Oru CBI Diary Kurippu' was the birth of the legend that beats justice with more brain than brawn - Sethuram Iyer, CBI. Essayed to perfection by the inimitable Mammooty, the movie is based on a case diary of a CBI investigation headed by Iyer. Suspecting foul play in a suicide of a young married girl, Iyer and his crack team of Vikram (Jagathy) and Harry (Suresh Gopi) get down to solving the mystery behind the death. Supported by a lingering theme song and a stellar cast, this movie's different approach {There were no songs nor heroines to distract Iyer :)} was eagerly lapped up by audiences, young and old alike.A classic movie. I rate it 10/10.
